I am a tile guy in your forum. I pose this question because I was wondering which trade should install the pan liner for a tile shower floor. The tile handbook recommends a "Pre-slope" under the liner and weep holes free and clear. I have been on jobs where the plumber installed the vinyl liner flat on the subfloor, nails it to the studs and then clamps it into the clamping ring of the drain. He feels he is done. If the tile man puts in a mudd base over the liner without adjusting it for a pre-slope the water that goes throught the deck mudd ( as it is supposed to) gets trapped. So, I ask again. Who puts in the shower pan liner in your area?

This would be a good question for Angus 242. He's also from Illinois and does them. He'll probably be around later.

Legally, the plumber is required to install it in most places... It has to pass a flood test and get signed off by the inspector.

Unfortunately, there's still a lot of plumbers who lay it flat on the floor, cut the liner at the curb corners and dont use the pre-made curb patches. In NY, we're required to have a lead pan still, and Massachusetts wants copper. Ugh!

You could skip the preslope-liner-final mudbed altogether and build a Kerdi shower... Get approval from the building inspector, and sell the homeowner on the benefits of a completely waterproof system.


If anyone ever needs a DVD for the Schluter stuff, send me an email... They come in the Kerdi drain boxes and I never throw them out... Still have a few laying around I could send.

I actually don't know who is responsible from the building departments point of view. From our perspective, we specify that the tile setter is responsible for preslope, liner and drain - just because of the flat liner problem you described. I should also note that our tile setter preferres it that way - if it leaks it's his problem.

If your asking because you feel your getting stuck with this responsibility - without compensation, start putting a line item on your quotes for installing preslope and liner. Also put a waiver on the quote for liners installed by others.

I do all my shower installs with the Kerdi system. I try and use the presloped pans whenver possible. If a standard pan won't work, I just do a presloped mud bed with the kerdi drain, and kerdi and tile the next day. Works great and it is a superior shower when done :thumbsup:. Other contractors in my area have the plumber install the pan liner directly on top of the subfloor as pgc555 mentioned above. I haven't looked in the TCA book in a while, but I don't think that is an approved method.

Thank you all for taking the time to respond.I think the tile setter should do everything for the reasons given by DaVinci . All responsibility goes to him alone and we tile setters would also prefer that.

When I was doing Co-op remodels it was a group effort, the carpenter built a sub floor sloped to the drain I installed, I laid the pan onto that presloped subfloor, either lead or poly, I prefer making lead pans, and then the tile installer made his base.

We do the pre slope.
The plumber installs the lead pan.
We follow that by laying the mud base.
We will be doing one shortly.

We give the tile contractor a chance to come in and do the pre slope and then our fiberglass guy comes in and covers it. If the tile contractor can't get there to do the slope then we have our carpenter do it.

As a plumber, Panning! when it was lead we did it. When the vinyl panning materials came out. We did it at the rough stages. Then we would go back and find drywall nails that went places that they shouldant and then got stepped on & put a little slice in the pan. Or we found tile setters nailing wire lath to the floor through the pan. Then when the leak occured the plumber would be sent back. Bad news! The pan work in my case was changed to the tile setter. He did the preslope, did the pan & then the tile.
Now when a leak occured the tile setter was sent back. BEAUTIFUL!
from a plumbing standpoint.

If you use a pan for the pre-slope, plumber.
If you use deck mud for the pre-slope, tiler.
