A bathroom quoted without a survey is a guess — and a guess with a price on it is a dispute scheduled for later. The photos you send are useful, but they can't show which way the joists run, what the water pressure is doing, or where the soil stack actually sits. This is what a proper survey covers, what to have ready, and what you should walk away with afterwards. It takes under an hour, it's free, and nothing about it commits you to anything.

Why quotes without surveys go wrong

Every bathroom price is really two numbers: the bathroom you can see, and the building around it. The second number is where unsurveyed quotes fall apart. A "£6,000 all-in" given from three photos hasn't priced the floor that needs levelling, the waste run that can't reach the new toilet position without opening the floor, or the fact that your mains pressure won't drive the rainfall head you've picked. Those discoveries don't disappear — they arrive mid-job as extras, when you have no negotiating position and half a bathroom.

A surveyed, fixed written price moves those discoveries to before the contract. That's the entire point.

What we actually check

Measurements — properly. Not just wall-to-wall, but window heights, door swings, ceiling height, and the true squareness of the room, which decides how tiles set out and whether that 1700mm bath genuinely fits or "fits" with a 20mm gap someone will fill with regret.

The floor and joists. Which way the joists run and what condition the floor is in determines what's possible: where a shower former can sit, whether the floor needs plywood or backer board, what a wet room conversion would involve. Upstairs bathrooms live or die by this.

The soil stack and waste routes. The toilet connects to the soil stack, and the soil stack is where it is. Moving a toilet even a metre means new drainage with real fall requirements — the survey establishes what's feasible and what it costs before anyone falls in love with a layout.

Water pressure and the hot water system. Combi boiler, unvented cylinder or gravity tank — each behaves differently, and the shower you want has a minimum pressure it needs. Measuring now prevents the most disappointing discovery in bathroom fitting: a beautiful shower that dribbles.

Ventilation. Where the extractor is, whether it actually discharges outside (a surprising number vent into the loft, quietly growing mould in the insulation), and what the room needs to keep condensation under control.

Electrics. What's there, what the new design needs — shower circuits, lighting zones, a fused spur for a mirror or underfloor heating — and whether the consumer unit can take it.

What you should have ready

Nothing formal. Useful things: pictures of bathrooms you like (a saved folder beats a description every time), an honest budget range, and your questions — all of them. Honesty about budget isn't a negotiating disadvantage; it's what lets us tell you where the money works hardest and what we'd cut first. If two decisions are still open — bath versus shower, say — say so. Pricing both options is normal.

What you get afterwards

A detailed, fixed-price written quotation clearly setting out the agreed scope of work — what's included, what's excluded, and the price that the finished job will actually cost. Not an estimate that firms up later. If we find something at survey that makes your plan a bad idea — a layout the drainage can't serve, a spend that the house won't repay — you'll hear it then, in plain terms, even when it makes the quote smaller.

You'll also get honest timings: what the job takes in working days and when we could start. If you're comparing fitters (sensible), compare their quotations line by line on scope — the bottom line only means something when the scopes match.

No, it's not a sales ambush

A survey is measurement, not theatre. There's no "today-only price", no sitting at your kitchen table until you sign, no deposit taken on the day. You get the written quotation afterwards, you compare it with others in your own time, and if the answer is no, that's fine — the survey cost you nothing either way. The trades with confidence in their pricing don't need pressure to defend it.
