Choosing a walk-in shower contractor: how to judge an installer

Four hundred and eighty searches a month look specifically for the contractor rather than the shower, and advertisers pay more for this click than for any other we measured in the category: $60.70 at the last pull, against remarkably little competition. That gap says something useful. Plenty of businesses want the customer who is ready to hire; far fewer are prepared to explain how they should be judged. Here is how we think an installer should be judged, ourselves included.

Start with the trade, not the brand

A walk-in shower is plumbing, waterproofing and tile, in that order of consequence. The wrong question is who has the most recognisable name; the right one is who will actually set the membrane and cut the drain in. Some firms install with their own crews, some sell the job and subcontract the work. Neither model is wrong in itself, but you are entitled to know which one you are buying, and to know who will physically be in your house.

The first visit tells you most of it

Watch what the estimator does. Measuring the room, checking what is under the floor, asking whether the user showers seated or standing, asking about walkers and doorways: these are the behaviours of someone pricing your bathroom. A figure produced from the doorway, or over the phone from photographs, is a figure produced without the facts, and the facts are what the price is made of.

Questions worth asking before money is discussed

• Who performs the work: your own crew or a subcontractor, and who supervises it?
• Which waterproofing system will be used, by name, and is a flood test done before tiling?
• Who applies for permits, where the jurisdiction requires them?
• When demolition uncovers damage, how is that change priced and approved?
• How long has the firm installed showers specifically, as opposed to bathrooms generally?

None of these is a trick. A capable installer answers all five without discomfort, and the answers are more informative than any brochure.

What a serious quote contains

A defined scope in writing: what is demolished, what is rebuilt, and what is excluded. The scope should read like the sequence of the work itself. Products named specifically enough to look up. An itemised price rather than a single figure. A payment schedule tied to stages of work, not loaded to the front. A stated method for change orders. And a validity period long enough to read it alone, sleep on it, and show it to someone else. A discount that dies when the salesperson leaves the house is not a discount, it is a deadline, and what a same-evening price really means is the same wherever the firm is based.

The waterproofing question sorts fastest

If one question has to do all the work, use this one: what keeps the water out of my floor, and how will you prove it before you tile? An installer who answers with a membrane system, named, and a flood test, described, understands the part of the job that fails years later when it is done badly. An answer built entirely around the tile is an answer about decoration. Why this is the part that matters is laid out on the shower conversion page, and why a curbless floor makes it critical is in the article on what sits under the tile.

What references are actually for

A reference from last month tells you the tile looked good on day one, which most tile does. More useful is a customer from years ago, asked two specific questions: has anything leaked or loosened since, and what happened when something unexpected came up during the work? How a firm behaves at the moment a problem appears is the thing you are really hiring, and it is the thing photographs cannot show.

Paperwork protects both sides

Where your jurisdiction licenses this trade, the number belongs on the quote and can be checked with the issuing body in minutes. A certificate of insurance is a normal thing to request and a normal thing to provide. Permits, where required, protect you twice: once through inspection, and again when the house is sold and the work has to be accounted for. A contractor who proposes skipping them to save time is offering to make their risk yours.
