Mustee 3434DTM – Frequently Asked Questions
1) What does a double threshold shower base mean, and when do I need one instead of a single threshold?
A double threshold base has two raised entry dams instead of one, so two adjacent sides of the pan are open for entry and the other two sit against walls. That is the configuration for a two-wall alcove or a corner shower. If your opening is a three-wall alcove with only one open side, a single threshold pan is the right call; on the Mustee 3434DTM you would be paying for a second dam you have no use for, and the wall side of a single threshold pan is finished to sit tight to framing.
2) What size drain does the Mustee 3434DTM shower floor take?
It takes a standard 2 inch drain assembly. Before you order, pull the rough-in location on your existing waste line and check it against the drain opening in the pan, because a square 34 x 34 base gives you very little room to shift the trap once the floor is opened up. On a conversion, the tub waste is almost never where the shower pan wants it, so plan on re-plumbing that connection.
3) Does a Mustee DURABASE shower pan need to be set in mortar?
Set it on a full-support bed. Mortar-bed or foam underlayment is the recommended method for the 3434DTM, and the reason is flex: a composite pan dropped onto bare joists or an uneven subfloor will move underfoot and telegraph that movement into the drain seal and the wall joint. Screed the bed flat, seat the pan into it, then set your wall surround. Budget the mortar or foam board as a separate line item on the job.
4) Is 3434DTM the Mustee model number for the 34x34 double threshold pan?
Yes, 3434DTM is the Mustee part number to order, and the suffix is what you are checking: DTM is the double threshold version of the 34 x 34 square base. The leading 3434 is the footprint. If a spec sheet or a takeoff calls for a single threshold pan in the same size, DTM is the wrong suffix and the pan will arrive with a dam on a side you meant to close off against a wall.
5) What is a Mustee DURABASE shower floor made of?
DURABASE composite. That is the same material family Mustee uses across its base line, and it is why these pans get specified in multi-family and light commercial turns: a molded composite pan is a single piece with no tile joints or grout to fail, so a unit turn is a demo, a set, and a surround rather than a re-tile. It goes in lighter than a cast pan, which matters when you are carrying one up to a second-floor unit.
