Luxury bathroom and wet-room refurbishment in Totteridge. Trusted, professional, 30+ years' hands-on experience.
A large Totteridge house often has a family bathroom, two or three en suites and a cloakroom, which turns a bathroom project into a hot water and drainage question as much as a tiling one. GS Renovation tanks properly, sets the falls correctly and certifies the electrical work, so the room stays sound rather than just looking right.

The complaint we hear most in big N20 houses is not the tiling, it is that two showers running at once turn into a dribble. A combi boiler sized for a semi cannot serve four outlets, so a house with multiple en suites usually needs a properly sized unvented cylinder, or a vented system with a decent pump, chosen against the actual simultaneous demand rather than the number of bedrooms. That decision is made before the sanitaryware is ordered, because a rain head with a low flow rate is an expensive disappointment.
Distance is the other issue on a wide plan. Where an en suite sits twenty metres of pipe from the cylinder, you wait, and you waste the water sitting in the pipe. A secondary return loop, or a small local water heater for a distant cloakroom, fixes it, and both are far easier to install while floors are up. We work this out at the design stage and lay the pipework accordingly, rather than discovering the problem on the morning the first person tries to use the new shower.
Every wet area is tanked before a tile goes on, walls and floor, with the membrane taken up behind the tray or across the whole floor in a wet room. Falls are formed to the drain and tested with water before tiling, not after, because a shower that ponds will find its way into the ceiling below eventually. Where a new bathroom sits above a habitable room in an older house, that discipline is the difference between a room that lasts twenty years and a repair bill in three.
Floors in the older village properties rarely start level, and joists in any house of age have usually been notched and drilled by earlier plumbers. We check the deflection before laying rigid tiles, strengthen or overlay where the engineer or the specification requires it, and route new waste pipes with the correct fall without cutting joists where they cannot take it. Electrical work, from the shower circuit to the extractor and the underfloor heating, is installed and certified under the relevant Approved Document and inspected as part of the building control record.
Bathrooms fail from behind the tiles, and in a large Totteridge house they also fail from an undersized hot water system that no amount of good tiling can fix. GS Renovation sizes the system for the real simultaneous demand, tanks and tests the wet areas before tiling, respects the floor structure it is working in and certifies the electrics. One team from strip out to final grout.

FAQ
Budget for the work itself plus a sensible contingency for what a survey cannot see. On a bay-fronted Victorian terraced property near N20 the usual unknowns with bathroom renovation sit behind plaster and under floors, so GS Renovation prices what is visible and flags the rest openly. The Barnet Council building control fee belongs in your Totteridge budget too. GS Renovation would rather over-explain a Barnet figure than surprise a Totteridge homeowner halfway through the work. As a rough guide, bathroom renovation in London ranges from roughly £6,000 to £20,000 or more (indicative London ranges, MyBuilder and Checkatrade, 2026). Your figure depends on the size, specification and condition of the property, which is why we survey before quoting.
Not if the application and the inspections are handled properly. GS Renovation submits early and books Barnet Council visits into the bathroom renovation programme so an N20 project is never waiting to be inspected before work can be concealed. Delays usually come from applying late, not from the authority itself. Your Totteridge completion certificate follows the final Barnet visit. GS Renovation attends the Barnet Council inspections at N20 so a Totteridge programme is not delayed.
Our founder has over 30 years of hands-on experience, and bathroom renovation is core work rather than an occasional job. We are on sites across Totteridge and Barnet most weeks, so the solid-wall Victorian terraces with original chimney breasts and suspended timber floors around N20 are familiar ground. GS Renovation is rated 4.9 from 31 MyBuilder reviews. Ask for addresses of finished work and go and look at it. Ring 07472 424 226 and we will arrange that. Ask on 07472 424 226 about comparable Barnet projects.
Yes. Bathroom electrics in Totteridge are notifiable under Part P and must be certified, and drainage, ventilation and any structural change must meet building regulations. GS Renovation includes certified electrical work and manages Barnet Council building control on every N20 bathroom.
It should not, and preserving them is usually worth the extra time. Bathroom renovation in solid-wall Victorian terraces with original chimney breasts and suspended timber floors can generally be routed around original detail rather than through it, and GS Renovation sets that out at the N20 survey. Where something genuinely cannot be saved you are told before work begins. Barnet Council may also have a view in a Totteridge conservation area. Ring 07472 424 226 and we will explain what bathroom renovation can and cannot save at N20.
Almost always because the hot water system is sized for a smaller house than the one you are in. A combi boiler delivers a fixed flow rate and splitting it between two outlets halves both. The usual fix in a large detached house with several en suites is a correctly sized unvented cylinder, chosen against your simultaneous demand rather than bedroom count, with the incoming main checked because a poor supply limits everything downstream. If the run to a distant en suite is long, a secondary return also stops you waiting for hot water. Decide this before ordering the showers.
We do not set one. What decides whether GS Renovation takes a bathroom renovation job at an N20 address is whether we can do it properly and when, not the size of the invoice. Small work in Totteridge often turns into a longer relationship. Call 07472 424 226 and we will tell you honestly if another Barnet trade suits you better. The survey costs nothing regardless. A modest job at N20 often becomes a longer Barnet relationship.
