Installing a kohler sonata shower

Installing a kohler sonata shower


Hi, first post here but been a reader for a long time. Anyways, I am building a new home a got a Kohler Sonata 60 1 piece shower. When it is in place, there is a gap of about 1 under the shower floor consistent with the specifications. The installation instructions say to shim the unit. The underside is obviously not completely flat so I wondered what if any support does it need? Its kinda disappointing that the instructions are so vague and it doesn't seem right that the floor pan would just hang there. Any info would be much appreciated! Thanks, Tom I am putting in a Sterling Accord shower made by Kohler myself so this is kind of a coincidence as I was checking out my own post. For the shower pan you need to put down a cement bed otherwise the shower pan can crack. Something I found out by reading up on Sterling products and asked my contractor about. You have to make sure that the concrete underneath though is pitched towards the drain but not so thick that the pan will not fit properly. If you are not sure about that you could hire someone or look up a video on You Tube that could guide you. Well that's what the instructions say to do. Some do not use mortar to bed them. http://www.us.kohler.com/onlinecatal.../1022476_2.pdf From the instructions: Be sure the bottom of the module is firmly supported against the floor. You may need to adjust some of the framing. Use shims as necessary. However, no additional support is required. The module must be plumb and level to ensure proper shower door installation. So, firmly supported against the floor means a mud bed then? From the installation instructions - Be sure the bottom of the module is firmly supported against the floor. You may need to adjust some of the framing. Use shims as necessary. However, no additional support is required. Supported across the front lip of the unit touching the floor and nailed to the studs per instructions. Mud bed would specifically be called out. no additional support is fairly clear although I can see where confusion could happen. I will give you a link to the instructions for the shower surround we are getting here is the link http://www.sterlingplumbing.com/onli.../1156426_2.pdf . Pay particular attention to instruction number 5. My contractor said he would never install this shower without a bed of cement underneath. I also now remember seeing a segment of Ask This Old House where they put in another shower surround and used a thin bed of mortar. The plumbers of the past used mortar under cast iron tubs too although not so much for strength but to keep the tub warm. Yes, I understand the logic behind the mortar bed. The question would be do so. The thing is one piece and weighs 200lbs. There would be no real way to place the thing on the bed. It would also take an awful lot of mortar to do so. As another person posted, the instructions make no reference to any sort of mortar bed. I stepped inside the shower in place and the floor is pretty thick and stout. Like I said, it would be nice if the instructions were more detailed but I guess it does say that no additional support is needed? I like to do things the proper way and I am torn on what to do... We have a plumber on the forum and I will send him a private message. He might advise the same thing. What you bought is nice but very hard to maneuver in one piece. If he does advise cement under the shower I advise you to get plenty of help in maneuvering the shower. I understand your feelings I am going through different thoughts but asking myself how do I do that for my remodel? Its hard to say.. Follow what the instructions suggest... In the past I used mortar for cast tubs. A recent sterling tub I was installing suggested a mortar base if the tub was not able to be leveled properly. Spray foam can be used too but if really out of level I would think the foam would flex some.. Of course I have used plaster before too... And when you shim what are you shimming with? That is on the bottom? I would not use wood and once you shim is may make the tub flex in that area if not totally supported in all areas. Thats where mortar comes in.
