Rated 1 out of 5 by from Good luck finding a Door that will work with this I see I am not alone in finding that the 36" pan has a 10" long tapered bumper on both sides. I purchased and installed 2 of these and now cannot find a compatible door. I talked to 4 people at HD. No help there.

Rated 1 out of 5 by from Avoid Count me as another victim of this flawed design. Installed the pan and enclosures and then realized the raised lip on the base makes the plan incompatible with just about any door -- Delta or otherwise. Called Delta Hardware and they suggested I try to trim a water diverter on the base of one of their doors. Come on!

Rated 5 out of 5 by from Easy Installation!! Great Fit!! Super Happy!! I bought this a month ago and very happy with the fit and the ease of installation!

Rated 1 out of 5 by from no door fits Delta responds w their Lindell glass. The photo shows a different pan. The kit walls are 72", the glass is 65 "too short. Still does not contour to the pan. Delta would owe so much money they have choice but to double down.

Rated 1 out of 5 by from Please do not but this product! I am so happy I haven’t installed it yet.. purchased it at Home Depot on the recommendation of the store employees, started our project and did a dry fit when my husband noticed the strange lip on the pan… started doing some more research and found countless reviews stating no door will fit.. Home Depot won’t take back the product since it’s outside their return window, delta won’t stand by their product and admit it’s a faulty design.. the only door that they have recommended is no longer available and nothing else fits .. please just save yourself the hassle and do not buy!!! Box should be labeled with a warning or product should be pulled from stores .. The delta rep I spoke to suggested I read the reviews next time… won’t be needing it, I simply won’t purchase delta again

Rated 1 out of 5 by from Terrible waste I bought this and had it installed, only to find out it has a useless funky lip on it. Then delta support says, "oh, we don't know of ANY door that will work with this pan". They should put a warning on this box of waste! Or better yet, take it off the market!

Rated 1 out of 5 by from Terrible if you want a shower door...WARNING! Bought this for my walk in shower, due to the partial lip on both sides no pivot or hinged shower door will work with it. Be warned if you want a shower door DO NOT GET THIS!

I purchased Classic 500 36x36 W Alcove Shower Pan Base with Center Drain in High Gloss White, Model #B12135-3636-WH. Floor is leveled. Can I staple tar paper on the floor then apply adhesive and finally install shower pan?

Asked by: John

The tar paper will not stick to the subfloor. This might cause movement and a squeaking noise when showering. Please contact us directly if you have any questions or need additional assistance.

What kind of shower door works with this pan since it has a lip on part of the threshold?

Asked by: gina342
Hi Gina342- curious whether this door or another worked for you.  My builder selected and installed this base now this crazy ridge/lip is creating shower door havoc.  Thank you.

This shower base has an elevated 1/2" tall bead on the sides of the front curb that makes installing a manufactured hinged door with flexible bottom seal impossible. Please let me know what kind of shower door will work with this unit. Thank you.
