Rated 4 out of 5 by from This new product has a very dense foam back which should reduce the chance of crack and leak. The dimension says 34 by 48 but the depth is actually only 33 inches so we had to install a decorative bar to conceal the gap between the shower base and the ceramic floor. Also, the acrylic surface is quite thin and easily scratched. The installer accidentally dropped his tool and it chipped a small piece on the base already. I hope the dimension is more accurate and the surface is more durable. Thanks.

What mortar/thin set do would I use for the shower pan base that is safe for polystyrene. No one at any of the hardware stores can tell me this information.

Hi, I just bought this model shower base, and I'm working through the install. My subfloor is not level, so I believe that I will have to set it in a mortar base. Do you have a recommended type of mortar that I should set this in? Thanks, mat

Does the base come with a drain piece? If not, what drain should be purchased?

Asked by: Jim M
Hello Jim M, Thank you for your question regarding the Delta Classic 400 - 48" X 34" Shower Base and I am happy to help you today. A drain assembly is not included with the purchase of this shower base. We recommend purchasing a standard shower drain. The drain will need to be placed 24" or 60.96 cm from the side wall and 16 1/8" or 42.23 cm from the back wall. I hope this helps and if there is anything further we can assist you with, please do not hesitate to give us a call on our warranty and technical support line at 800-355-2721. Thank you, Brandy

Hardi Backer and TIle

How big of a gap is needed between the backer board and the base, as well as the tile and the base?
Asked by: KJ
Hello KJ, Thank you for your question on the Delta Classic 400 48" X 34" Shower Base. I would be happy to help you with this question. As shown in step seven in the installation guide for this shower pan, you can stop the backer board just above the flange for the shower base and bring the tile down to the base. After installing the walls, you will want to apply an adhesive to the edge where the base meets the tile to prevent leakage. I hope this was helpful! If you have any other questions about this product you can call 800-355-2721 for answers and assistance. Thank you, Caleb Delta Faucet Company
