I installed cement board just above the lip. The screws used to attach the pan to the wall studs are just slightly recessed underneath this under the lip. How should waterproofing and tile be installed to hide the screws and fill this gap?

I would like to put down a mortar bed even though it's not required. Can you provide guidance on a particular product to use? Thanks.

Asked by: Tom S
Hi Valued Customer, Thank you for your question, please accept our sincere apology for the inconvenience you are experiencing. We will be happy to assist you in resolving this issue as quickly as possible. No. The shower base is designed to rest directly on the subfloor. Only if the floor is unlevel would mortar or leveling compound be needed. A general "sand mix" mortar type will be sufficient. Please feel free to contact us directly for technical information at 800-345-3358. We are available Monday through Friday from 8 a.m. to 8 p.m. and Saturdays from 9 a.m. to 6 p.m. Eastern Standard Time. Thank you for being a loyal Delta Faucet customer. Best Regards, Themar Digital Communications Specialist (800) 345-3358 customerservice@deltafaucet.com

Can this be installed in a mobile home if I have the space for the 48x34 Model # B12135-4834-WH & wall set Model # B12205-4834-WH?

Asked by: Kathy
Hi valued customer, Thank you for your question about the Delta Faucet model B12135-4834-WH. This installs directly to wall studs. See the installation manual for the required wall stud placement. https://media.deltafaucet.com/MandI/113867%20Rev%20C.pdf The walls and sub-floor must be solid, plumb, and level. Do not install in areas where temperature may drop below 32ºF. If the sub-floor is not flat and level, a mortar bed must be used. Please reach out with any additional questions! Best Regards, Bryan Digital Communications Specialist
