Thread: Tub to Shower Conversion

    Default Tub to Shower Conversion

    I am remodeling a bathroom in my home, which is on a slab. I would like to replace the 30 x 60 tub with the swanstone 32 x 60 retrofit shower base. My question is in reference to venting of the new shower stall. The main vent is 3" cast iron. My sink is approximately 24" c/l of drain to the left and drains into the 3" vent and the toilet connection is directy in front of the vent.
    The tub drain c/l is approximately 36" to the right of the cast iron vent. The existing tub drain is 1-1/2" and I believe converts to 2" below grade. Some literature that I read indicates that a vent should be within 5' of the trap and following the run of the drain I should be within that criteria. Do I need to install a dedicated shower vent or not. By the way there is a slab rough in at the tub drain area that is approximately 14" x 14" so I have a little room to work, howerver this would obviously be covered by the new base and would be difficult to vent there.

    Thanks
    Rick

    One thing you'll need to do is break up the concrete to get to the 2" line...the drain to a shower is required to be 2" in most locals. The drain also is usually installed in the middle of the shower, too. If you'd like to consider a tiled shower, take a look on www.schluter.com and look at their Kerdi product...really neat, and probably less than the thing you were looking for. Also, check out www.johnbridge.com on tiling questions.

    Default Top Five Steps to plan your "Tub to Shower Conversion".

    I got a call yesterday that the plumber on the most current job site is not familiar with how to replace a tub and plumb the new drain for a shower.

    Most times the drains are in the center of a shower but when you remove a tub the drain is at one side.
    This is an easy fix and using a linear shower drain makes for a one way slope.

    You can also grade your floor and use just a single point drain. The options are all your.


    Converting a tub to a shower. Here are five Ideabooks to get you started. The articles on Houzz are design related. Here on Terry's site you will get the meat and potatoes of the build. One simple thing to do when planning a tub to shower conversion is to set up an account both here on Terry Love's forum but also on Houzz. Then you can post questions in either venue as you need help.

    What I like most about this is the extra eyes you place on the job.

    Convert Your Tub Space to a Shower

    Step 1 - The Planning Phase

    Step 2 - The Fixtures-Shopping Phase

    Step 3 - The Tiling and Grouting Phase

    Step 4 - Waterproofing and Drainage

    Step 5 - Choosing Accessories

    The reason the waterproofing and drainage step is after the tile and grout step is because this is a design session. It is not until you understand the end design that you can pick the right products to waterproof a shower.
