Bathroom Renovation Morden

GS Renovation renovates bathrooms across Morden, from family bathrooms in 1930s terraces and semis to new en-suites carved out of interwar bedrooms. Houses across SM4 often have a single dated bathroom over the kitchen that owners want reworked. We handle the waterproofing, drainage, tiling and finish from start to finish.

In Morden, a full bathroom refit typically costs £6,000 to £20,000 or more (indicative London ranges, MyBuilder and Checkatrade, 2026). GS Renovation Ltd, a building contractor based in Potters Bar, does the work in Morden: we carry the tanking, plumbing and tiling as one contract, with the electrics certified by a registered electrician.

How the job runs

1. Free design visit at your Morden home and an itemised quote.
2. Strip-out, then first-fix plumbing and electrics.
3. Tanking to the wet areas, then tiling.
4. Sanitaryware and second fix, with notifiable electrics certified by a registered electrician. Typically 10 to 15 working days on site.

Wet rooms and en-suites in Morden

In Morden's interwar houses a slice of a bedroom can often take an en-suite, or the main bathroom a walk-in shower, without cramping either room. We tank and waterproof the whole wet area properly before a single tile goes on, because getting the membrane right is what stops leaks reaching the rooms below. Correct falls to the drainage and good ventilation keep the finished room dry.

For a wet room we set the floor to fall towards a concealed drain and tank the substrate fully, so water goes where it should. We can add underfloor heating under the tiles, fit thermostatic showers, and plan the layout around the existing soil stack to keep the pipework runs sensible. In a 1930s house that often means working with the original bathroom position over the kitchen.

Housing in Morden

About 9,990 homes are listed for Morden, and the mix is 75% houses to 25% flats, with 17% built after 1945, 81% in 1919 to 1939 and 2% earlier. 64% of homes here are terraced; a terrace bathroom in Morden vents front, back or up, never into a party wall.

A downstairs WC under the stairs in a Morden house

A downstairs WC often features in a Morden renovation brief, and 81% of homes here were built between 1919 and 1939, when the space under the stairs was normally left as a cupboard. Turning it into a WC depends on three things. Headroom at the door end has to allow someone to stand at the basin, which usually fixes the pan at the low end. The waste has to reach a drain with a proper fall, often by running along the hall to the rear or out through an outside wall. And the room needs a fan ducted to outside, since it has no window.

The stair itself sets limits. The strings and carriage that hold up the flight often run through the space, and cutting them to gain a few centimetres of headroom weakens the stair. Any change to the stair structure goes past the structural engineer we appoint first. The walls of the new WC are best built in studwork lined with moisture resistant board, so the hall is not made narrower than it needs to be. Plan the Morden WC with the hall floor, the gas meter and any cupboard under the landing in view.

Space-saving bathrooms in Morden's 1930s homes

Where the original bathroom is on the small side, clever planning makes it feel far bigger. We use wall-hung sanitaryware, recessed niches in the tiled walls, and slim shower enclosures to free up floor space, then light the room to open it up. On the interwar houses around SM4, boxing in the soil pipe neatly and squaring off odd corners often reclaims usable room that was going to waste.

Every bathroom we build is properly waterproofed, ventilated to control condensation and finished with quality tiling and fittings. We manage the drainage, the plumbing and the electrics, with the notifiable electrical work certified by a registered electrician under Part P. Because one team does the lot, from strip-out to the final grout, there is no waiting on separate plumbers, tilers and electricians, and your Morden home stays clean and usable throughout.
