How to Quote a Bathroom Renovation: The Complete UK Contractor Guide

Bathroom renovations are one of the most competitive spaces in UK residential trades. Homeowners typically get 3–4 quotes, and the difference between winning and losing often has nothing to do with price.

This guide gives you a solid quote structure for bathroom work, how to price the job accurately, and how to present your quote in a way that makes it the obvious choice.

What to Include in a Bathroom Renovation Quote

A bathroom quote needs to be comprehensive. Homeowners asking for bathroom quotes have often been stung before — by surprise extras, hidden costs, or work that wasn't as complete as they expected. Transparency wins trust.

1. Full Scope of Works

Break the job into phases and list every element. For a full bathroom renovation:

Preparation / Strip Out

Remove existing suite (bath, WC, basin, shower)
Remove existing tiles (floor and/or walls)
Remove existing flooring
Cut out and cap existing plumbing to allow new layout
Dispose of all waste

First Fix

Plumbing rough-in for new layout
Electrical first fix (fan, lighting positions, shaver point)
Tanking / waterproofing to wet areas (specify product and method)

Tiling

Wall tiling (specify area in m², specify who supplies tiles)
Floor tiling (specify area)
Grouting and silicone sealing

Sanitaryware Installation

Bath: [manufacturer, model, colour — or "customer supplied"]
Toilet: [as above]
Basin / vanity unit: [as above]
Shower enclosure: [as above]

Second Fix

Completion of plumbing (connect all sanitaryware)
Electrical second fix (fan, lights, heated towel rail)
Install accessories (mirrors, toilet roll holder, towel rails)

Finishing

Make good any disturbed plasterwork
Silicone all joints

2. Exclusions

Be explicit about what's NOT included:

Any structural issues discovered during strip-out
Mould remediation behind existing tiles (quote separately if found)
Decoration outside the bathroom (e.g. hallway making good)
Furniture delivery (if customer supplying sanitaryware)
Building regulations / sign-off (if applicable)

3. Tiles — Supplied by You or the Client?

This needs to be clear upfront. Either:

"All tiles supplied and fitted by us — [tile reference and price per m² stated]", or
"Customer to supply all tiles. Our quote covers adhesive, grout, sealant and fitting only."

Ambiguity here leads to disputes. If the client is supplying tiles, note that your start date is contingent on tiles being delivered to site before works commence.

The Mistake That Costs Bathroom Fitters the Most Jobs

Bathroom fitters consistently lose jobs not on price, but on presentation. Three contractors quote £5,500, £5,800, and £6,200 for the same job. The client picks £5,800 — not because it's in the middle, but because that quote was the clearest, most professional, and included photos from the site visit.

The £5,500 quote was too vague. The client worried there'd be extras. The £6,200 quote didn't follow up.

Presentation and professionalism at the quote stage signal what the actual work will be like. Clients make this connection subconsciously. A sloppy quote suggests a sloppy tradesman.

For a bathroom renovation specifically — where clients will live with the result for 10+ years and are spending real money — visual proof is particularly powerful. Being able to show a before/after visualisation of the finished bathroom before work begins builds excitement and removes doubt.
