What Tools Should a Bathroom Remodeler Bring to Your Home?

“We use quality materials” is what everybody says, and on its own it means nothing. A method and a model number mean something, because you can check them.

Ours is a DeWalt DCE400D2 cordless PEX expander kit — $569 at Lowe’s. The model number is right there if you want to look it up. A hand crimper, which is the tool the cheaper method needs, is a fraction of that.

Why does the expansion tool matter?

Cold-expansion connections, covered by ASTM F1960, only work with PEX-A. The tool expands the pipe and a reinforcing ring so a fitting can be inserted, and the pipe’s shape memory shrinks it back down onto the fitting.

That means the tool cannot be used with cheaper PEX-B. Buying it is a decision to run the more expensive pipe from then on. It is a tool that makes your own materials cost more, which is why it is a reasonable signal of what is going into the wall.

What does the rotating head do?

The feature that matters is one you would never notice: the head rotates automatically between expansions, so the pipe opens evenly the whole way round. Pro Tool Reviews, testing the cordless expander we use, put the risk plainly — if the head only expands in one place, “you risk getting a leak on that joint, as the PEX tube has not been uniformly stretched.”

An unevenly stretched pipe pulls back unevenly, and you have built a leak that shows up in year three. A rotating head means an installer cannot get that wrong by being tired at the end of a long day.

What else is worth asking about?

• Which grade of PEX is being run, and how the joints are made
• Whether the plumbing is pressure-tested before anything is covered
• Whether blocking for grab bars goes in while the wall is open
• What is written into the warranty afterward, and who stands behind it

Does better tooling mean a longer job?

No. Anything standard and in stock — a tub-to-shower conversion, a walk-in shower, a walk-in tub — is installed within three to five days from the date of sale, and each of those is a single-day installation. Those are two separate numbers and they are worth keeping apart: three to five days is the wait until we arrive, and one day is the work itself.

The reason we can do that is inventory. We carry the materials, including all fourteen wall colors, rather than ordering them after you sign. Champagne bronze fixtures and doors are the one exception; they are not stocked and run up to seven days, which is a ceiling we do not exceed.

What to do with this

You do not need to become an expert on plumbing tools. You need two or three specific questions that are hard to answer vaguely. Which pipe, which joint, and what gets written down — those three will tell you most of what you need to know about a crew.
