Questions & Answers
5 questions

Can they be custom made to fit certain atea

The Arc Trudek shower foundation can be cut to desired size and shape using common tools to fit almost any installation.

Can I get a ark shower base that will fitt where a left handed tub was.

Arc shower pans can be cut to fit with a standard carbide blade. Please contact us directly if you have any more questions.

Can they be installed on top of the subfloor if you’re not concerned about a curb less application

Yes, technically they can be installed on top of the subfloor but the manufacturer states that this is not the recommended installation method for this product.

Can you make a 78” x48 “ shower foundation?

Yes. The easiest way is to get the 59 x 47-1/4 size and install a pitch extension on either end, then manipulate that by cutting it down to length.

I would like to order 47x59 base, however it says I need a commercial address? So it can't be used in a residential home?

Commercial address only refers to shipping. It has nothing to do with the product installation. For delivery purposes, this product must be delivered to a commercial location with a forklift or loading dock for liability reasons with our carrier. If you require residential delivery, that can be arranged as well. Please call our customer service team at 1(800)709-0002 should you need further assistance.
