How much does it cost to reseal a bathroom?

Resealing a single bath or shower typically costs £90-£180, while a full bathroom (bath, shower and sink together) costs around £220-£380.

Why has my bathroom sealant failed?

Sealant naturally degrades over time, and poor original application or slight movement in the building can cause it to crack or lift early.

Is resealing cheaper than fixing water damage?

Yes, resealing costs a fraction of what repairing damp or rot caused by water getting behind failed sealant would cost.

Do you offer bathroom resealing as a standalone job?

Yes, we can reseal an existing bathroom without requiring a full renovation.

Bathroom Sealing & Resealing Cost Guide (2026)

Failed or mouldy sealant is one of the most common small jobs we get called out for, and it's far cheaper to fix early than to deal with the water damage that follows if it's left. Here's what professional resealing typically costs in the UK.

Written by the team at The Bathroom Project — hands-on bathroom, plumbing and heating specialists serving Bromley, Orpington and across Kent.

Typical resealing costs

Per NearMeTrades' bathroom resealing guide, a standard bath reseal costs around £90-£160, a shower cubicle reseal around £110-£180 (higher due to vertical joints and glass), and resealing a full bathroom — bath, shower and sink together — around £220-£380 at a discounted combined rate.

Regional variation

Location affects price too: BookABuilderUK's guide notes that a professional resealing service typically costs £80-£160 nationally, rising to £120-£180 in London and the South East, largely due to minimum call-out charges.

Why it's worth doing promptly

Sealant naturally degrades over time and can fail early if poorly applied or if the building moves slightly. Once water gets behind tiles through failed sealant, the repair bill for the resulting damp or rot is far higher than the cost of resealing itself.
