Yes, you can have fitted wardrobes in a room with underfloor heating. The design just has to respect the heating from the first drawing. That means a base that lets air move, fixings that avoid pipes and cables, and a floor plan agreed before anyone picks up a drill.
Done badly, a sealed, flat-bottomed wardrobe traps heat, wastes energy and can stress both the furniture and the floor. Done well, you will not notice the heating at all, apart from clothes that are never cold to put on.
This guide covers the decisions that matter, in the order you will meet them: which heating system you have, how the wardrobe base should be built, how to fix units safely, what the floor finish does to heat output, and what to ask any fitter before you sign.
TL;DR
- Fitted wardrobes can sit over underfloor heating, but a sealed, flat base can trap heat. Ask for a raised or ventilated plinth instead.
- Get an “as-built” drawing of your pipe or cable layout before the fixing plan is finalised, and avoid deep fixings into the floor.
- Heat output depends on the whole floor build-up. The Energy Saving Trust advises keeping carpet and underlay to a combined 2.5 tog or lower.
- Plan the wardrobes, the heating and the floor finish together, in that order of thinking, and finish the floor before the wardrobes go in.
- We design around your heating, with soft-close fittings as standard and a 10-year guarantee on workmanship.

Why wardrobes and underfloor heating need planning together
Underfloor heating works by warming the floor, which then warms the room. There are two main types. Wet systems circulate warm water through pipes. Dry or electric systems use cables or mats. The Energy Saving Trust explains both types and notes that the right choice depends on the property and how you use it.
A fitted wardrobe is the opposite of a freestanding one. It is built to the ceiling and wall, usually scribed tight to the floor, and it covers a lot of floor area. In a typical double bedroom a run of fitted wardrobes can occupy a whole wall. If that wall sits over live heating zones, you are placing a large, insulating box on top of the heat source.
The Energy Saving Trust’s advice on heating controls makes a related point: heat sources and thermostats need a free flow of air, so large immovable furniture should not block them. A wardrobe will not usually block a thermostat, but the principle applies to the floor too. Heat that cannot leave the surface has to go somewhere.
There are three practical consequences:
- Efficiency. Covered floor gives less heat to the room. One supplier guide suggests that blocking part of the heated floor with heavy furniture can reduce efficiency, and recommends leaving clearance underneath furniture.
- Materials. Trapped heat can dry and warp timber-based carpentry over time.
- The heating itself. If heat cannot dissipate evenly, the area beneath can run hotter than designed.
None of this is a reason to give up on fitted storage. It is a reason to specify it properly.
Know your system before you design
The first question we ask on a design visit is what is under the floor. The answer changes the design.
Wet (water-based) systems
Wet systems run at relatively low flow temperatures. The Energy Saving Trust says they are often the better long-term choice for whole-house heating because they suit heat pumps and efficient boilers. Pipes are typically laid in screed or in boards over insulation, so the floor build-up can be thick and the pipe runs spread across most of the room.
For wardrobes, the main questions are where the pipes run and how the floor is built up. A wet floor is usually less prone to sharp hotspots than a high-output electric mat, but it still needs airflow.
Dry (electric) systems
Electric systems tend to be used in bathrooms, dressing rooms and extensions, where you want short bursts of warmth. The Energy Saving Trust notes they are generally more expensive to run at standard electricity rates. Cables or mats sit close to the surface, often under a thin floor finish, which makes the fixing question more sensitive. A long screw in the wrong place can damage a cable.
If your dressing room or walk-in wardrobe is the zone with electric heating, tell us at the start. We will plan the layout so that the heated area and the cabinetry work together instead of competing.
If you are not sure
Check the installer’s handover pack, the property survey, or ask the heating engineer who commissioned the system. In older London homes where heating was added during a renovation, the documentation is sometimes missing. In that case, a thermal imaging survey or a pipe-locating check by a heating professional is worth paying for before any wardrobe work starts.
How the wardrobe base should be built
This is the heart of the matter. A conventional fitted wardrobe has a plinth: a recessed or boxed base, usually 70 to 100 mm high, that hides the floor junction and lets you stand close to the doors. There are a few ways to handle that plinth over heated floors.
| Base option | How it works | Best for | Watch out for |
|---|---|---|---|
| Raised, open plinth | The carcass sits on a recessed frame with a gap along the front or sides, so air can move beneath | Bedrooms with wet or electric heating | Needs a neat finish so the gap looks designed, not left over |
| Ventilated plinth | Discreet slots or a perforated plinth panel allow air to circulate | Full-height runs over heated zones | Slots must stay clear of clutter and shoes |
| Standard closed plinth with heating-free footprint | The wardrobe sits only on floor that has no heating under it | Rooms where the heating was zoned away from walls | Needs a reliable drawing of the heated area |
| Wall-hung or floating carcasses | Units are fixed to the wall and sit above the floor | Shallow runs, dressing rooms, media walls | Wall construction must carry the load |
The Which? guide to planning fitted wardrobes recommends leaving a small ventilation gap or choosing a design that lets air flow, particularly on external-facing walls where condensation can build up. Underfloor heating changes the thermal behaviour of a room, so the case for airflow gets stronger, not weaker.
A supplier guide to furniture over underfloor heating suggests clearance of around 3 to 5 cm beneath flat-bottomed pieces. That is a general figure for loose furniture, not a rule for built-in carpentry, and your heating installer’s guidance for your specific system comes first. We would treat it as a starting point for the conversation, not a specification.
A note on external walls
Wardrobes on cold external walls attract condensation even without underfloor heating. Add a warmer floor and the air inside a tightly sealed carcass can change temperature and humidity in ways that matter for clothes and timber. Our guide to fitted wardrobe ventilation requirements goes into the detail of gaps, back-panel treatments and air paths.
Fixing wardrobes without damaging the heating
Fitted wardrobes are fixed to walls, ceilings and sometimes floors. Of the three, the floor is the one to treat with respect.
Government-backed guidance on solid floor insulation stresses that the floor finish and build-up must protect the heating system and that installation design should account for the weight and fixing points of anything heavy placed on top. That guidance is aimed at insulation and retrofit work, but the logic carries straight over to cabinetry.
In practice, we recommend this routine:
- Ask for the as-built drawing. Your heating installer should be able to give you a layout showing pipe or cable positions. Photographs taken before the screed or boards went down are also valuable.
- Mark the no-drill zones. On the day of the survey, note where fixings must not go.
- Fix to the walls first. Most of a wardrobe’s load can be carried by wall fixings and a scribed top frame, which keeps floor fixings shallow or unnecessary.
- Use shallow, short fixings at the base if needed. Never drive long screws through a heated floor build-up on an assumption.
- Check again at fitting. If anything has changed on site, the fitter pauses and checks before drilling.
The point is not to alarm you. Pierced pipes and cut cables are rare when work is planned, and expensive when it is not.
Floor finish: the part people forget
What sits on top of the heating matters as much as what sits on it. Three finish questions come up repeatedly.
Carpet
If your bedroom is carpeted, the Energy Saving Trust advises that the combined tog rating of carpet and underlay should be 2.5 or lower. Higher figures significantly slow the room’s heat-up time. This applies to the floor the heating serves, and it is another reason to avoid piling extra insulating layers under a wardrobe base.
Engineered wood, laminate and tile
These conduct heat well and are common in rooms with underfloor heating. If you plan to lay a new finish, do it before the wardrobes go in. That also avoids the awkward situation of a fitted unit sitting on a floor that is a few millimetres higher or lower than the finished one. Our article on when to install fitted wardrobes explains why finishing floors first saves money and trouble.
Rugs
The same Energy Saving Trust guidance on heating controls cautions against covering heat sources with heavy rugs. A thick, felt-backed rug in front of a wardrobe works against the heating in exactly the area where you stand. Breathable, thinner rugs are the safer choice.
What underfloor heating costs, and why it matters for the wardrobe budget
If you are installing or upgrading underfloor heating as part of the same renovation, the cost of the heating will usually dwarf the cost of working around it. The Energy Saving Trust gives estimated installation costs of £50 to £85 per square metre for dry systems and £85 to £110 per square metre for wet systems, varying with complexity and whether it is part of a larger project.
That has a practical meaning. A 14 m² bedroom is a different heating cost from a 5 m² dressing room, and it can be worth heating only the part of the floor not hidden by furniture. If your wardrobes will cover a whole wall, ask the heating installer to leave that strip unheated and to zone the room accordingly. You save money on the heating and remove the overheating risk in one move.
We do not publish wardrobe prices, because every design is made to the room and priced after a visit. If you want a feel for what drives cost, see our guide to floor-to-ceiling wardrobe costs.
Planning the heating and the wardrobes as one project
Government guidance on solid floor insulation encourages treating floor works as part of a long-term plan. It points out that laying pipes over insulation, even if you do not connect them straight away, can make a later move to low-temperature heating much easier and avoid disruptive work after the furniture is in.
The same thinking applies to wardrobes. If you are renovating, the best order is usually:
- Agree the room layout, including where the bed, doors and wardrobes go.
- Share that layout with your heating installer so the zones follow the plan.
- Lay the heating and the floor finish.
- Survey for the wardrobes, with the pipe or cable drawing to hand.
- Manufacture and fit.
If the heating is already in, steps 2 and 3 are done, and we work from what exists. Our guide on how to plan fitted wardrobes properly walks through the wider planning decisions.
Our perspective
We build fitted wardrobes across West London and the surrounding areas, and underfloor heating comes up more often every year, especially in extensions, loft conversions and full refurbishments.
Our view is simple. A wardrobe should be designed around the room it lives in, and the heating is part of that room. We would rather spend an extra ten minutes on the survey, asking what is under the floor and where it runs, than guess.
Here is how we approach it:
- We ask first. On the free design visit we ask about the heating type, its zones and any drawings you have.
- We design the base to suit. That might be a raised plinth, a ventilated one, or a layout that avoids heated zones.
- We keep floor fixings to a minimum. Walls and scribed frames carry the load wherever the build allows.
- We use soft-close fittings as standard, so doors and drawers close quietly and cleanly, whatever the room temperature.
- We stand behind the work with a 10-year guarantee on workmanship.
The things we will not do are seal a flat-bottomed wardrobe over live heating without telling you, or drill into a floor we have not checked. If a plan carries a risk, we will say so and offer a better design.

Design ideas that suit heated floors
Heated floors do not limit style. They steer a few choices.
Floating-look plinths
A recessed shadow-gap plinth looks deliberate and lets air move. It suits modern fitted wardrobes, with handleless doors or slim profiles, and it keeps the cleaning line tidy.
Sliding doors
Sliding wardrobes keep the footprint tight and do not need door swing space, which helps in smaller rooms where the heated area is limited. See our sliding wardrobes for how they work in different rooms.
Walk-in wardrobes and dressing rooms
This is where electric underfloor heating is most often used, since you want gentle warmth for short periods. Open shelving, hanging rails and drawer units on legs or raised bases suit this well. Concealed lighting adds to the feel, and our concealed lighting guide explains how to plan it, including wiring routes that stay clear of the floor.
Loft and sloped rooms
Loft conversions often have new heating and tight spaces under the eaves. Bespoke sloped wardrobes use every inch, but low sections near the floor are the ones most likely to sit over heating. We design these with ventilated bases or leave a deliberate heating-free strip.
Media walls
A TV media wall generates its own heat from equipment. Placing it over a heated floor calls for the same airflow thinking, plus ventilation for electronics. We cover media walls under our services.
Questions to ask any fitter
Before you commit, put these questions to whoever is quoting for your wardrobes, us included.
- Have you worked on rooms with underfloor heating, and how do you adapt the base?
- Will you ask for the as-built drawing and mark no-drill zones on site?
- How will air circulate beneath and behind the units?
- What fixings go into the floor, and how deep?
- What happens if you find something unexpected when drilling?
- Who removes and disposes of the old wardrobe?
- How long from survey to fitting, and what guarantee comes with the work?
A good fitter answers these without hesitation. Vague answers are a signal to keep looking. Our guide to what to expect from a wardrobe installation sets out how the process runs from our side.
What fitting looks like with us
After a free design visit, we design and make your wardrobes to the room. Installation is typically quick: we aim for around seven days in most cases, and a larger or more complex project can take a little longer, up to around twelve days. We also take away and dispose of your old wardrobe as part of the job.
If your room has underfloor heating, the visit is where we gather the information that shapes the design. Bring any drawings, the installer’s details and photos of the floor build-up if you have them.

FAQ
Can you put fitted wardrobes on underfloor heating?
Yes, as long as the design allows heat to escape and fixings avoid pipes and cables. A raised or ventilated base is safer than a sealed, flat-bottomed plinth. Agree the approach with your heating installer and your wardrobe fitter before the units are made.
Will a fitted wardrobe damage my underfloor heating?
It should not if planned properly. The risks come from trapped heat and from drilling into the floor without knowing where pipes or cables run. Ask for an as-built drawing and keep floor fixings shallow, or fix to walls wherever possible.
Should the floor under my wardrobes be heated at all?
Often it is better not to. If wardrobes will cover a strip of floor permanently, ask your heating installer to leave it unheated, which saves installation cost and removes the overheating risk. If the heating is already installed, a ventilated base is the usual solution.
What carpet can I use over underfloor heating in a bedroom?
The Energy Saving Trust advises a combined carpet and underlay rating of 2.5 tog or lower so heat can pass into the room efficiently. Check the labels before you buy, and fit the finished floor before the wardrobes go in.
Is electric or wet underfloor heating better for a dressing room?
The Energy Saving Trust suggests electric systems suit small comfort zones such as bathrooms or dressing rooms, while wet systems often suit whole-house heating. For a dressing room or walk-in wardrobe, electric is common, but it costs more to run, so zone it carefully.
