There are two kinds of people in the world: those who've stepped onto a warm bathroom floor on a cold January morning, and those who haven't yet. If you're in the second group, you're going to want to read this.
We're delighted to introduce Cosytoes to the Brand New Bathrooms family, a British manufacturer with nearly two decades of expertise in electric underfloor heating, and quite possibly the solution to the one bathroom frustration that no amount of designer tiles or chrome taps can solve: the bone-chilling cold floor moment.
Cosytoes is now available exclusively in our heating range, and this guide covers everything you need to know, what underfloor heating actually is, how the Cosytoes system works, which products suit which bathrooms, and why we're confident this is one of the most useful additions we've made to our range in years.
Who Are Cosytoes?
Cosytoes are a British manufacturer of electric underfloor heating systems and when we say British, we mean it. Their products are designed and made in the UK, which sets them apart in a market often dominated by imported alternatives. They've been at it for nearly twenty years, supplying UK and European customers with heating solutions that combine genuine quality with practical installation.
Their philosophy is straightforward: the best underfloor heating system is one that's properly made, properly supported, and properly guaranteed. Which is why every Cosytoes cable and mat comes with a lifetime guarantee — not a five-year warranty, not a ten-year limited cover, a lifetime guarantee. That's a level of confidence that tells you something about the product.
All Cosytoes products comply with UK and EU safety standards, and their underfloor heating cables are manufactured to meet EN 60335-2-96:2002 — the specific British and European standard for electric floor heating in wet areas. In short: these are products you can trust in a bathroom environment, including wet rooms.
Why Underfloor Heating in Your Bathroom?
Cold floors are the most obvious problem that underfloor heating solves. But it goes further than that. Here's why more homeowners are making UFH a non-negotiable part of their bathroom plans:
1. Consistent, Even Warmth
A heated towel rail warms one corner of your bathroom. A radiator creates hot patches and cold spots. Underfloor heating warms the entire floor surface evenly, which means the whole room reaches a comfortable ambient temperature, not just the bit nearest the heat source.
2. It Frees Up Wall Space
No radiator means more wall space for furniture, for tiles, for a mirror that doesn't have to compete for position with a chrome panel. In the compact bathrooms where every square inch matters, this is genuinely significant.
3. The Running Costs Are Lower Than You'd Expect
Heating a small bathroom with Cosytoes can cost as little as 25p per day. The TradeMat Plus system uses approximately 1p per hour per square metre in a modern home which, when paired with a good timerstat, means you're only ever heating the floor when you actually need it.
4. It Works Under Almost Every Floor Type
Tiles, vinyl, stone — Cosytoes underfloor heating is compatible with the vast majority of bathroom flooring types. And because the cables and mats are just 3mm thick, there's no significant change to floor height.
5. It's Suitable for Wet Rooms
All Cosytoes cables and mats carry an IPX7 waterproof rating, making them fully suitable for installation in wet rooms, one of the most popular bathroom styles right now. That's not a given with cheaper alternatives.
Think of Cosytoes underfloor heating as the invisible upgrade — no one sees it, but everyone who steps into your bathroom notices it.
The Cosytoes Range: What's Available at Brand New Bathrooms
The Cosytoes system is built around three core product types — the heating element (mat or loose cable), the installation support board, and the control unit (thermostat or timerstat). Here's how they break down:
Cosytoes TradeMat Plus — The Flagship Heating Mat
The fast-install, best-selling choice for most bathrooms
The TradeMat Plus is the product that built Cosytoes' reputation, and it's easy to understand why. It's a pre-formed heating mat, the cable is already spaced and fixed to a mesh, so there's no measuring cable runs or fixing individual wires to the floor. You unroll it, stick it down, and tile over it.
The 'Tack n Stick' adhesive backing on the underside of the mat makes installation particularly straightforward. The mat grips the floor during installation, which makes it significantly easier to position accurately — especially important when you're working around obstacles like toilet bases or basin pedestals.
-
150W per square metre — powerful, effective floor warming
- Only 3mm thick — minimal change to floor height
- 'Tack n Stick' adhesive backing — stays in place during tiling
- Fixed cable spacing ensures even heat distribution across the floor
- IPX7 waterproof — suitable for bathrooms and wet rooms
- Lifetime guarantee on the cable
✅ Perfect for: Most bathrooms undergoing a tile refresh or full renovation. If you're getting tiles laid anyway, this is the logical time to add UFH underneath — the additional cost and installation time is minimal.
Cosytoes Loose Cable System — For Irregular Spaces
When the room doesn't play by the rules
Not every bathroom is a simple rectangle. Alcoves, chimney breasts, awkward corners — the TradeMat works brilliantly in regular spaces, but the Loose Cable system is the answer when your floor plan has other ideas.
The loose cable is fixed to the floor manually using fixing tape, following the spacing guides in the installation documentation. It's slightly more time-consuming to install than the mat, but it gives complete flexibility in how you cover an irregular floor area — no sections of mat have to be cut, no heat loss from gaps in coverage.
- Ideal for irregular, non-rectangular floor areas
- 3mm thick cable — no change in floor height
- Fixed to floor with adhesive tape following spacing guide
- Tile directly over once installed
- IPX7 rated — wet room suitable
- Lifetime guarantee
✅ Perfect for: Bathrooms with complex layouts, alcoves, or floors that need cable run around fixed features. Also worth considering for rooms where sections of the floor are covered by furniture and don't need heating.
Control Units: Thermostats
Underfloor heating without a good control unit is like a car without a steering wheel — it'll work, but not particularly efficiently. Cosytoes offer a range thermostats to suit every preference, from simple touch-screen units to full WiFi-enabled smart controls.
This controls both when the heating comes on and off, and the target floor temperature — meaning you only heat the floor when you need it, which keeps running costs to a minimum.
The Curve — WiFi Thermostat
The Curve is Cosytoes' smart timerstat, and it's the option most of our customers opt for. It connects to your home WiFi router and can be controlled from anywhere via the Cosytoes app — available on Android and iOS. Coming home early? Switch the heating on from the car. Going on holiday? Switch it off from the airport.
- WiFi connectivity — control from anywhere via app
- 7-day programmable memory — different schedules for each day
- Ultra-slim 3mm touchscreen design
- IPX7 waterproof rated — suitable for bathroom installation
- Holiday function — suspend heating while you're away
- Key lock function — ideal for households with children
- Available in White, Black, and Anthracite finish
The Mirage — Smart Thermostat (Non-WiFi)
The Mirage is the Curve's non-WiFi sibling — all the smart functionality of programmable timing and temperature control, without the app connectivity. A solid, good-looking timerstat for those who prefer simple, reliable control without the need for smartphone integration.
- Programmable timerstat — set your schedule and forget
- Contemporary design — available in White and Black
- Efficient and simple to operate
The Vista Dual — The Premium Choice
The Vista Dual is Cosytoes' latest and most capable control unit. It features a colour widescreen display, full WiFi connectivity, and uniquely, the ability to also control a heated towel rail via the same thermostat and app. One unit, complete bathroom heating control.
- Colour widescreen display — horizontal or vertical orientation
- WiFi connected — full app control
- Controls both underfloor heating AND a heated towel rail
- Available in White and Black
- The ultimate smart bathroom heating setup
How Easy Is It to Install?
More straightforward than most people assume — particularly with the TradeMat Plus. The 'Tack n Stick' adhesive backing means the mat stays in position while you work, and the pre-spaced cable removes the need for any measuring or calculation of cable runs.
The general installation process for a TradeMat Plus system is:
- Prepare the subfloor
- Unroll and position the mat in the heated area
- Use the Tack n Stick backing to fix the mat in position
- Connect the cable to the timerstat (electrical connection by a qualified electrician)
- Lay floor adhesive and tiles over the mat
- Set up the timerstat once tiling is complete
The electrical connection should always be carried out by a qualified electrician but the mat positioning and tiling can be handled by a competent bathroom fitter or experienced DIYer. Cosytoes provide full installation guides and documentation with all products, and their customer support team is known for being genuinely helpful if questions arise during installation.
⚠️ Important: Never cut the heating cable during installation — doing so will void the guarantee. If the mat needs to change direction around an obstacle, use the mesh backing only, never cut through the cable itself.
Who Is Cosytoes Underfloor Heating Suited To?
The honest answer is: almost anyone planning a bathroom renovation. But here are the situations where it makes the most compelling case:
- Full bathroom tile refresh — if the tiles are coming up anyway, now is the ideal time to lay UFH underneath. The additional cost is modest; the benefit lasts decades.
- New build or major renovation — easy to incorporate into the build programme from the start without disrupting existing flooring.
- Wet rooms — IPX7 waterproof rating makes Cosytoes one of the few systems genuinely safe and suitable for wet room environments.
- En-suite upgrades — TradeMat options are sized specifically for compact en-suites. Warm floors in a small space are disproportionately satisfying.
- Families with young children — a warm bathroom floor at 7am is a quality-of-life improvement that every parent will appreciate immediately.
- Anyone replacing a radiator — removing a bathroom radiator and installing UFH instead creates useful wall and floor space.
