An individual room needs an individual quotation
Allow around £15,000–£25,000 as a total budget for a complete bathroom renovation, covering labour, building materials, tiles, bathroom fittings and finishes. Products you buy yourself are part of this total. This is a planning range, not a minimum spend or a fixed quotation. Room size, layout and product choices affect the cost. Tell us your budget so we can discuss what is achievable after a free site visit.
Room preparation and installation work
The condition of the existing room and the agreed layout affect the work involved. Discuss removal of the existing fittings, preparation of walls and floors, plumbing, electrical work and finishing as part of the written scope. Where work requires certification, the relevant documentation is provided.
Tiles, bathroom fittings and finishes
Tile sizes, surfaces, bathroom fittings and storage choices affect both product costs and installation requirements. Discuss the room layout and the products you are considering before finalising purchases.
Products you purchase directly still count
We can supply the agreed products, or you can purchase them yourself. Your written quotation distinguishes the work, building materials and products we supply from your separate purchases.
When comparing quotations, add your own purchases to the contractor’s quoted work and supplies. Check which selections remain open and what allowances and exclusions are stated.
How your purchases fit into the total
For illustration, £12,000 for our agreed work and supplies plus £6,000 of tiles and bathroom fittings purchased by you makes an £18,000 total project budget. These figures explain the calculation; they are not a quotation or a record of a previous project.
Working with your budget
Share your intended budget even if it falls outside this guide. We can discuss the room, your priorities and product choices before preparing a quotation. Keeping a practical existing layout and choosing standard product sizes can help control costs. More extensive work and higher-specification products can take the total above the guide.
What can increase the budget?
More extensive layout changes, the condition of existing services or surfaces, access arrangements and higher-specification products can change the scope. Discuss these at the site visit. Additional work and changed selections should be described and agreed before proceeding.
What should the written quotation explain?
- The preparation, installation and finishing work included.
- The building materials and products supplied by BathWright.
- The items you will purchase separately.
- Assumptions, exclusions and choices that remain to be resolved.
- The proposed programme and how changes will be discussed.
Allow time for preparation as well as the build
Typically 2–4 weeks on site, depending on the agreed scope. Preparation, ordering and the start date are discussed separately.
