Luxury bathroom and wet-room refurbishment in Kennington. Trusted, professional, 30+ years' hands-on experience.
GS Renovation refits bathrooms across Kennington, fitting wet rooms, en-suites and family bathrooms into the Georgian and Regency townhouses of SE11. With more than 30 years across Lambeth, we get the waterproofing, drainage and ventilation right first time, which matters most in period homes with original timber floors and solid walls.

Water and period timber floors are an unforgiving combination, so every Kennington bathroom we build starts with proper tanking. We fully waterproof the shower zone and, in a wet room, the whole floor, bonding the membrane before a single tile is laid. On the suspended timber floors typical of these SE11 townhouses, we make sure the substrate is rigid enough for stone or large-format tiles, because movement is what cracks grout and lets water into the structure below.
Drainage and ventilation are the other two pillars. Rerouting waste through a period floor takes planning to keep the falls right without notching joists beyond what is safe, and we extract humid air properly so damp does not settle into the surrounding plaster and joinery. Underfloor heating goes in under the tanking where the floor build-up allows, giving a warm floor and helping the room dry, which is welcome in these older Kennington houses.
Bathrooms in Kennington's period homes are often carved out of what was never designed to be one, a landing return, a former closet wing or a corner of a bedroom. We plan layouts that make the most of tight or awkward footprints, using walk-in showers, wall-hung sanitaryware and slim vanities to keep floor space visible and the room feeling larger than it is, while still respecting the proportions of the house.
En-suites are a frequent request, tucked into a bedroom in these taller SE11 townhouses, and we route the services and ventilation so the new room works without disturbing the floor below. Internal bathroom work does not need planning permission, though the electrics are notifiable under building regulations, so the wiring and any extractor are certified as part of the job and signed off correctly.
In Kennington's period homes, a bathroom that leaks or fails to ventilate quickly damages timber floors and original plaster, so GS Renovation gets the tanking, drainage and extraction right before the tiling ever starts. With 30+ years in SE11, we deliver wet rooms, en-suites and family bathrooms that are watertight, warm and built to suit the age of the house.

FAQ
Usually the structural work and the making good, in that order. Steel, propping and the engineer's design account for the largest share of a bathroom renovation job at an SE11 address, and reinstating a Georgian and early Victorian interior afterwards accounts for more than most people expect. The Lambeth Council fee is small by comparison. GS Renovation shows all three separately on the Kennington quotation. Ring 07472 424 226 and we will explain the balance at an SE11 property. 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.
The whole sequence is set out for you at the start. Survey, quotation, engineer where bathroom renovation needs one, Lambeth Council approval, then construction at the SE11 property, each with an indicative duration. GS Renovation updates a Kennington client weekly once work begins. That way nobody in the Lambeth household is guessing when the house comes back. Ring 07472 424 226 and GS Renovation will set out the whole sequence for an SE11 home in Kennington.
Paperwork is where bathroom renovation projects quietly lose time, so we take it on. GS Renovation runs the Lambeth Council application and inspections for your SE11 property alongside the works programme, which keeps the Kennington job moving. The engineer's design, where the structure requires one, is coordinated by us as well. You receive the certificate at completion. Ring 07472 424 226 to hear how a Lambeth application runs. The certificate matters when a Lambeth property changes hands.
Part F sets the requirement, and in practice that means mechanical extraction to outside, never into a loft void. Condensation is a persistent problem in Kennington's older solid-wall properties, so we size extraction properly at the SE11 address rather than fitting the smallest unit that complies.
Always. Applying a standard detail to Georgian and Regency townhouses, many listed or within conservation areas is how original features get damaged, so GS Renovation plans bathroom renovation around what the SE11 property actually is. The engineer's design covers the structure; the finishing is matched to what is already in the Kennington house. You agree both before work begins in Lambeth. Ring 07472 424 226 and we will explain how bathroom renovation is matched to the finishes already present in an SE11 home today.
Yes. A wet room works well in a Kennington townhouse provided the floor is prepared correctly, because these homes usually have suspended timber floors that need a rigid, fully tanked substrate before tiling. We handle the waterproofing, drainage falls, ventilation and optional underfloor heating, and certify the electrics under building regulations. No planning permission is needed for internal bathroom work in SE11.
Yes, both. Bathroom renovation in an SE11 flat brings the lease and the freeholder's consent into it, which is the main practical difference from a Kennington house, and GS Renovation will explain what applies before any design work. Building control still goes through Lambeth Council. Ring 07472 424 226, describe the block, and we will tell you what is involved. The survey across Lambeth is free either way. The freeholder's licence to alter comes first at SE11.
