Bathroom InstallationIn Manchester,One Team Start To Finish

Wet areas are boarded with tile backer board or a suitably moisture-resistant board fixed to a sound, rigid framework. Plasterboard behind a shower is the most common failure we strip out — it may hold for a couple of years, but once water reaches it the tiles come away with the board.

Deflection matters as much as moisture. Tile is unforgiving of movement, so floors are stiffened or overboarded where the existing structure flexes, particularly in older suspended timber floors in Victorian and 1930s properties.

Wet zones are tanked with a liquid membrane or matting system, with corners, junctions and pipe penetrations taped and sealed. The membrane is the waterproof layer; the tile is a wearing surface and the grout is porous. Any installation that treats grout and silicone as the waterproofing will leak eventually.

In wet rooms this extends across the whole floor with the membrane dressed into the falls and around the drain. Falls are formed to the gully so water leaves rather than sits, and the drain is set so the finished tile height works with the door threshold.

Supply pipework is run in copper or barrier plastic with isolation valves at each appliance, so a future tap change does not mean draining the house. Concealed valves for wall-mounted brassware are positioned with access in mind, not simply buried.

Waste is the constraint that most often dictates layout. Every waste needs sufficient fall to the stack, and moving a WC in particular is limited by soil connection and fall. This is checked at survey, which is why we set out the layout before quoting rather than after.

A mixer shower needs balanced pressures and adequate flow. On a combi system the shower is limited by the boiler's flow rate; on a gravity-fed system it may need a pump; on an unvented cylinder there is mains pressure available at both hot and cold, which is why cylinder work and bathroom work so often go together.

Thermostatic mixing is standard for scald protection, particularly where an unvented cylinder stores at high temperature. Where the existing supply cannot deliver what the customer wants, we say so at quote stage and set out what would need changing.

Towel rails look good but usually emit far less than the radiator they replace, which leaves a cold bathroom in January. Where a rail is the only emitter, output is checked against the room's heat loss, and underfloor heating is often the better answer beneath a tiled floor.

Underfloor in a bathroom frees the wall entirely and makes a tiled floor comfortable underfoot. It is straightforward to include while the floor is up, and impossible to add cheaply afterwards.

Extraction is not an afterthought. An adequately rated extractor, ducted properly to outside rather than into a loft void, with overrun or humidity control, is what keeps moisture out of the fabric and mould off new grout.

Ducting into a loft is a genuinely common find during strip-outs and causes damp in the roof space rather than solving anything in the bathroom.

Level-access and walk-in shower conversions are regular work — removing a bath, forming falls, fitting a low-profile tray or a tiled wet floor, and adding grab support where needed. It is a change that keeps a house usable for people who should not be climbing into a bath.

En-suites in loft conversions bring their own constraints: soil connection, headroom over the shower and whether a pump is needed to lift waste. Rental refits are specified for durability and easy maintenance, since a bathroom in a let property has a harder life than one in an owner-occupied home.
