Service Overview
A full bathroom installation is a multi-trade project — plumbing, tiling, electrics, plastering, joinery and decoration — coordinated to land on a fixed timeline and a fixed price. We handle the lot, from initial design through to the last bead of silicone.
Homeowners refreshing a dated bathroom, families adapting space for accessibility or growing kids, landlords adding value before sale or refinancing, and anyone who's been quoted by three separate trades and wants one number to call instead.
Whenever the existing bathroom is becoming a daily friction. Common triggers: tiling crazing, taps and showers past saving, layout no longer suiting how the family uses the room, or a slow shower-tray leak that's quietly damaging the ceiling below. Bathroom projects typically book 4-8 weeks ahead.
A bathroom done badly leaks, looks tired in five years and has to be done again. A bathroom done properly — waterproof tanking under tiles, correct fall on the shower, decent extraction, isolation on every supply — lasts two decades. The difference is almost entirely in the prep work nobody sees.
The Cost of Waiting
Most failed bathrooms fail in predictable ways:
Our Process
01
Home visit, measurements, discussion of layout, fittings and finish. Mood-board options if helpful.
02
Written quote covering supply (or supply-only-fit), labour, materials, waste removal and a project timeline.
03
Old suite removed, room stripped to substrate, electrics first-fix, plumbing first-fix, tanking applied where needed.
04
Walls and floor tiled, suite installed, electrical second-fix, lighting and extraction commissioned.
05
Silicone, decoration touch-ups, full leak test, deep clean, photographic handover record.
Why Choose On-Tap
One project manager, one phone number. No coordinating trades yourself, no finger-pointing if something goes wrong.
Preferred pricing from suppliers we use weekly — savings passed on, not absorbed.
Tanking, correct falls, proper isolation, decent extraction. Boring details that determine bathroom lifespan.
Floors swept, dust contained, debris removed end of every day. We keep your home liveable through the project.
Itemised, transparent, no surprise extras. Variations agreed in writing before any extra work.
Most family bathrooms complete in 7-12 working days, on a timeline agreed before we start.
In Depth
The visible parts of a bathroom — tiles, suite, taps — are 20% of the work. Here's the 80% that determines how long it lasts.
Any wall and floor surface within reach of regular splash needs a continuous waterproof membrane behind the tiles. We use either a liquid-applied tanking system (BAL WP1, Mapei Mapelastic) or a sheet membrane (Schlüter-KERDI) depending on the substrate. Critical detail: all internal corners and pipe penetrations sealed with reinforcing strip. Without this, water tracks behind tiles through grout joints and starts the slow rot that ruins ceilings below.
Hot and cold supplies routed in copper or compliant push-fit, with full-bore isolation valves on every outlet — basin, bath, WC, shower. Wastes correctly sized (32mm for basin, 40mm for bath/shower, 110mm for WC) and laid with proper fall (minimum 1:40) to a vented stack. Pressure tested before any boards or tiles go on.
Bathroom electrics fall under Part P of the Building Regulations — we work with qualified electricians for all certifiable work. Lighting designed for zones (IP65 in zone 1 and 2, IP44 in zone 2 outside the shower), with extraction sized properly (minimum 15 litres/second for a typical family bathroom, ducted to outside — never into the loft).
Tile substrate (cement board over noggined timber, or directly onto solid wall) checked flat to within 3mm over 2m before tiling. Tiles laid with full-coverage adhesive (no spot-bedding), grouted with flexible cement-based grout, sealed with neutral-cure sanitary silicone at every internal angle. Final clean, full leak test on every outlet, with a 12-month workmanship guarantee.
Typical mid-spec family bathroom (suite supplied by us, full strip-out and re-fit, decent tiling and lighting): £8,500-£14,000. High-spec or larger en-suites with bespoke joinery can be £15-25k. Free design visit, fixed-price written quote.
Standard family bathroom: 7-12 working days. Larger or multi-bathroom projects: 2-4 weeks. We'll always give you a written timeline before the project starts.
Yes — we'll fit anything water-regs compliant. We can also offer trade pricing on most major brands (Lefroy Brooks, Hansgrohe, Vitra, Roca, Geberit, Mira, Aqualisa) if that helps.
Yes — strip-out, skip hire and disposal are included in the quoted price.
Yes — managed end-to-end. Certified electrician for any notifiable work, plasterer for any re-board or skim, decorator for paint finishes. One project manager, one invoice.
Yes — fully tanked, level-access wet-rooms with linear or tile-insert drains, formed-fall floors and slip-resistant tiling. Particularly popular for accessibility-focused refits.
Honestly: bathrooms are messy and you'll need an alternative for 7-10 days. We minimise impact (dust-control sheeting, daily clean-up, contained work zone) but it's not a quiet job.
