Bathroom Renovation Price: What to Expect and How to Budget

Thinking about giving your bathroom a fresh look? You’re not alone—homeowners love the boost a new bathroom gives to comfort and resale value. The first question that pops up is always the same: how much will it cost? In this guide we break down the main cost drivers, share realistic price ranges for 2025, and give you simple tricks to keep the spend under control.

What Drives Bathroom Renovation Costs?

Every bathroom remodel has three big expense buckets: fixtures, labour, and finishes. Fixtures cover the bathtub, shower, toilet, sink, and any specialty hardware. Labour includes plumbers, electricians, tilers, and the general contractor who coordinates the work. Finishes are the tiles, paint, lighting, and accessories that make the space look finished.

On average, a mid‑range bathroom remodel in the UK runs between £8,000 and £15,000. If you stick to basic porcelain tiles, a standard white toilet, and a prefabricated shower unit, you can stay near the low end. Go for high‑end marble, a freestanding bathtub, or custom cabinetry and the price can climb past £20,000.

Size matters too. A small guest bathroom (around 3 m²) will cost less than a master bath (5 m² or more) simply because there’s less material and fewer hours of labour. However, larger spaces often need more complex plumbing runs, which can add a few thousand pounds.

Another hidden driver is the condition of the existing space. If you have water damage, outdated wiring, or need to move walls, those extra prep tasks can quickly inflate the budget. Always budget a 10‑15% contingency for surprise issues.

How to Keep Your Bathroom Renovation on Budget

First, set a clear budget before you pick any tiles or fixtures. Write down the maximum amount you’re comfortable spending, then allocate percentages: 40% for fixtures, 35% for labour, and 25% for finishes. This split helps you see where you can trim without hurting quality.

Second, shop around for supplies. Big chain stores often have sales on tile and vanity units, while local suppliers may offer discounts for bulk orders. Don’t forget to compare online retailers—shipping can be free if you hit a certain spend.

Third, consider a phased approach. If the biggest headache is the bathtub, replace that first and plan to upgrade the vanity later. Spreading work over a few months can ease cash flow and let you take advantage of seasonal discounts.

Fourth, reuse what you can. If your current toilet is in good shape, keep it. Recycling existing cabinets or countertops can shave a few hundred pounds off the total.

Finally, get multiple quotes from reputable contractors. A detailed estimate that breaks down every line item lets you compare apples to apples. Beware of lowball offers that skip essential permits or insurance—those can cost you more down the line.

In short, a bathroom renovation price isn’t a single number; it’s a range influenced by size, materials, and the work’s complexity. By understanding the main cost drivers and following these budgeting tips, you can achieve the bathroom you want without breaking the bank.
