Bath Replacement Cost: What You'll Pay in the UK

Replacing just the bath — leaving the toilet and basin in place — typically costs £400-£1,500 in total, including the new bath and fitting labour, for a standard-sized acrylic or steel bath in roughly the same position as the old one.

What affects the cost

• Bath material: acrylic baths are the cheapest, typically £100-£300; steel baths sit a little higher, often £150-£400; cast iron and freestanding baths cost considerably more, frequently £500-£2,000+ for the bath alone.
• Size and shape: a standard straight bath is the cheapest to buy and fit; corner baths, freestanding baths and non-standard shapes cost more both to buy and to install, since standard tiling and panelling often don't fit around them without extra work.
• Labour: removing an old bath and fitting a new one in the same position typically takes a day, at roughly £150-£350 in labour depending on your region — more if tiling or flooring needs repairing afterwards.
• Access: baths in awkward spots (upstairs, through tight doorways) can add cost, particularly for heavy cast iron or stone-resin baths that need more than one person to carry.

What's often forgotten

Removing an old bath frequently reveals problems that weren't visible before — damaged flooring, damp subfloor, or tile damage where the old bath panel sat. Budgeting a contingency of 10-15% on top of your bath-replacement quote is sensible, particularly in an older property.

DIY or professional?

Removing an old bath is a manageable DIY job, but connecting the waste and taps for the new one is plumbing work with real consequences if done badly — a poorly sealed bath connection can cause hidden leaks that damage floors and ceilings over months before they're noticed. Most homeowners have at least the plumbing connection done by a qualified plumber.

Common mistakes

• Choosing a bath before checking it fits through doorways and stairwells — this is a genuine problem with larger baths in older properties with narrow hallways.
• Not checking the waste and overflow positions match between old and new baths, which can mean extra plumbing work if they don't line up.
• Skipping a bath support frame on lightweight acrylic baths, which can lead to flexing, cracking, and sealant failure over time.

Repair or replace?

Not every tired-looking bath needs full replacement. If the bath itself is structurally sound but the surface is scratched, stained or has lost its shine, re-enamelling (sometimes called resurfacing) is worth considering first — it typically costs £200-£500 and can extend the life of an otherwise good bath by several years. It won't fix chips, cracks or a genuinely outdated shape, but for cosmetic wear alone it's a meaningfully cheaper option than full replacement.

What a typical quote should include

When comparing bath replacement quotes, check whether they include: removal and disposal of the old bath, the bath panel (front and end panels are sometimes priced separately), sealant, any tile repair where the old bath's edge sat, and reconnection of waste and taps. A quote that excludes the panel or tile repair can look cheaper on paper while leaving you with unexpected extra costs once the old bath is out.

If you're replacing more than just the bath, see our guide to full suite replacement costs, or if you're considering swapping the bath for a shower entirely, our bath-to-shower conversion cost guide covers that specific project.
