Bathroom Renovation in Harlow

Walk-in showers cost less to build than bath-plus-screen setups, use less space, and suit ageing-in-place. Keep at least one bathtub in the home if you may sell to families — in most markets a home with no bath at all narrows the buyer pool. If you have two bathrooms, the common answer is one of each.

Around 10-20% is normal, sometimes more where custom vanities or imported fittings must be ordered up front — in that case pay the supplier invoice share, not a round 50%. Hold 5-10% back until the room has been used for a week or two and the snag list (grout gaps, silicone, door alignment) is closed.

Run every fixture: check drainage speed, look under the vanity for weeps, confirm the shower floor falls to the drain (pour a bucket and watch), check grout lines are even and silicone is continuous, and test the extractor fan. Photograph everything and get the waterproofing product and warranty terms in writing before releasing final payment.

A straight swap-in-place refit takes about 1-2 weeks; a full renovation with new waterproofing, retiling, and any layout change takes 2-4 weeks. Add waiting time before the start for fixture delivery and trades scheduling — and note that waterproofing membranes need curing days you cannot compress.

If the renovation strips the shower area back to the substrate, waterproofing must be redone — a failed membrane is the most expensive bathroom defect there is, because the fix means demolishing finished tiling. Several countries regulate wet-area waterproofing explicitly. Never let a contractor tile directly over an old or damaged membrane.

Checkatrade's 2025-26 guide puts a new bathroom including materials at £5,500-£8,000 with an average around £7,000; budget refits can come in near £3,000-£4,500 and large or high-end bathrooms run £14,000+. Fitting labour alone is typically £1,500-£4,000 depending on scope.

A straightforward refit takes about 5-10 working days; layout changes or first-floor drainage rework push it to two to three weeks. Book fitters ahead — good bathroom installers in most UK cities carry 4-8 week lead times.
