USG Durock Pre-Sloped Shower Pan Kit

The Durock Shower System makes waterproofing shower installations easier and faster. With a 3-pound density, the molded expanded polystyrene (EPS) shower tray is exceptionally strong, offering greater support for the tile covering in shower applications. Designed with an optimal 2% slope, it's also more comfortable to stand on and easily accepts a wide variety of tile shapes and sizes. Despite its strength, this lightweight shower tray easily cuts with a knife, is dust free and comes in four standard sizes. Includes all of the components you need to build a fully bonded, waterproof shower system that is made to accept tile covering. The preformed, pre-pitched shower base can easily be installed as the pieces become perfectly interlocked. The drain assembly and shower tray disk will connect to a PVC or ABS connection, as both connections are included within the shower system. The tray disk will help you vertically and horizontally align the drain grate assembly.


  • Easy-to-position drain assembly that accepts all Durock Shower System 4" and 5" grate options - Click Here for Grate Options (Comes with all pieces needed for grate installation)

I need a 48" X 60" shower kit with offset drain and 60" curb.
What do you recommend?

This size would require a custom shower pan please call 800-709-0002 or email orders@contractorsdirect.com for more information.

This kit does not include the grate... correct? When I look up grates, that includes things like the construcuctionn plug, grate tray, etc... are these included in the shower kit? I just want to make sure I have what I need and not duplicates. Thank you!

Correct the grate is not included in the kit and the items that come with the grate are just included with the grate and not the shower kit so no duplicate items will be received.

Can you please provide the dimensions and location of the offset drain? The distance from the center of the drain to edge of shower pan in both directions would be helpful. Am I missing something?

The drain is 12" from the sides edges of the pan on each side. From the center of the drain to the side edges on the pan is 16".

Is the sloped shower floor waterproof without the membrane?

The shower tray needs to have thinset applied on top of the pan and then needs to be waterproofed with the waterproofing membrane.

What is the thickness of the pan

The pans thickness is 1 inch

4/23/2019 12:33:47 pm


Unfortunately there is kit with that pan size at this time.

What are the dimensions of the two curbs? I will have the 60" length and 32" depth that will need curbs.

The dimension of the curb is 48"x5"x4".

I need 32 x40 offset drain can 20 inches be cut off one side only

It is not recommended to just just one side of the pan as it can mess with the pitch. It would have to be trimmed evenly on each side. We can also get you pricing on a custom size pan that would be a much better fit. Contact us at orders@contractorsdirect.com for details.

do you need to tape the seams on the durock walls before you apply the membrane

The seam tape or waterproofing band is to be applied at the same time as the membrane. You would first lay the membrane on the walls and then the seam tape in the corners where the membrane meets. This video linked below shows a demonstration of the proper installation.

Is there a general Square Foot Cost for Custom Pre-Sloped Pans?

Cost of the pan will be calculated once the form has been completed and sent to our email orders@contractorsdirect.com. We then submit this form to USG, and they get back to us with a quote.

Can curb height be cut without compromising waterproof integrity?

The USG curb can be cut to any size you prefer.

8/13/2019 12:12:01 pm

What type of thinset do you use to put the pan down and fabric

You can use tile-setting mortar meeting ANSI A118.1, A118.4, A118.11 or A118.15 for this shower system.

Is the curb strong enough to hold a shower door?

Yeah, the curbs are able to hold up a shower door.

11/18/2019 10:12:42 pm

Can you use this system as a curb less installation on either or at least two sides?

Yes, please see this USG Durock Brand Shower System Barrier Free Installation Video for further details.

I don't see a metal drain with bottom flange. What's used for center drain hook up?

The USG Durock Brand Drain Assembly is an ABS drain body that is very durable and comes with all the hardware needed to connect the center drain to the plumbing.

How does this (much less costly) kit compare to others on the market (Schluter, etc.), it seems similar in design? I am re-doing a second floor master shower and can't decide to do the usual mortar/pan or this type. And, does the curb have a little slope built into it?

The USG Durock Brand Shower Kit comes with all the components required to create a full shower system at a cost effective price. All you need to add is a drain grate. It is our top selling shower system. The Schluter system requires you add pipe collars and corners and the full drain assembly.

The foam shower pan is becoming ever popular as a replacement for standard mud pans. It cuts down on set up and clean up and takes a lot of guessing out of the installation.

The curb does not have a slope built in.

I watched the installation video and it shows cutting out the subfloor. I thought you don't have to on these kits. Also where do you get the metal chrome grate? Does it come with a 60" x 32" middle drain kit? Thanks

You do not have to cut out the subfloor if you are making a shower with a curb. You need to make the shower pan flush with the shower floor if you want to make a curbless shower.

The other products are made by USG Durock, however, Contractors Direct does not distribute these items.

You can select a 32" x 60" Center Drain kit above.

The only thing missing from kit number 3256 is the metal drain cover 3071. I see them priced separately, is this correct? Thanks

That is correct. The last component you need is the drain cover. You can choose either 4" or 5" drains and choose from the USG Pro Series or Designer Series grates.
