My workshop bathroom/utility room designs
I'm planning to add a bathroom/ utility room onto my workshop come spring, weather permitting of course. These are my designs. I'll explain them in better detail.
Cheezy, if you have been pondering my crazy pics on Flickr, look no further. Here's a better description. My plan is to do a simple bathroom with utility room capabilities. When I come in from riding motorcycles, I am usually covered in road goop and sometimes mud if I have been off road. My criteria are simple, run in type shower with no pan, no shower curtains, and no doors. The floor will be concrete like the rest of the workshop. The bathroom will get a floor drain. The shower will slope to it. Toilet, utility sink, hot water, and a place to wash gear will be useful. I own some mobile homes and I always have spare appliances, toilets, sinks, ect.. My first version came out like this. A bit too big. the plumbing would be a nightmare. I don't really need the dryer or a large shower. The shower is in a bit of a bad place to be a run in shower. I am a big guy and my home tub/shower is 22"x48". To narrow for my liking but plenty long enough. I went overboard big on the shower. I could take the SO in there with me. OOO LA LA. My second version is much smaller and may be what I end up building. I got rid of the dryer, scaled back the shower size, and rearranged some things. The dryer needs a direct vent outside which restricted me to an outside wall with it. Also, I wanted as straight of a run as possible to my septic system for the plumbing. This smaller version allows the shower/floor drain to drop right into the 4-inch main septic pipe. The 4-inch pipe starts under the toilet. The water heater pressure valve will be plumbed around behind the toilet, along the bottom of the wall, and a 45-degree elbow on the end of the pipe will direct water into the shower/floor drain. The washer will pump it's water into the utility sink. The pipe for the sink will run directly into a 4-inch to 2-inch Y fitting. when the 4-inch sewer pipe clears the building slab, there will be a 45-degree turn and straight run into the septic system. The roof air vent for the septic system will be directly behind the toilet in the wall. The way I plan to run the cold/hot water plumbing, it can be drained back through the outside faucet and also out through the hot water heater. Anyone that's done plumbing will get it. I can't do plumbing diagrams on a PC. |

I'm intrigued by your project, and I have a couple of thoughts. First, you'd prefer your initial toilet layout, simply so you don't have to reach behind for TP.
Why does the dryer require a direct vent? Is it gas fired? Even if it is, they have remarkably low emissions; my parents have been venting the same gas dryer indoors since 1978. Not joking. Since it's a workshop and not a domicile, nobody will be sleeping in there. Can you vent out the roof? Since the washer drain is pumped, it might splash more than you'd like into the utility sink; might be worth your time to glue up some ABS that is dedicated to the washer. I really like how you plan to be able to drain the system down through the hose bib. I don't think I would have considered that.

I started my workshop project September of 2016. My health happened and I missed the last half of 2017 and the first half of 2018. During that time, I spent a lot of time thinking about the bathroom/utility room addition. We don't get a lot of freezing weather here. Sure we get a lot of nights where it dips below freezing but it doesn't stay there. Even though the shop will be heated when I'm working, it won't be insulated. The bathroom might get insulation because of the plumbing. I decided it would be a good idea to be able to drain the entire plumbing system. Other than hand washing and maybe toilet, I don't think I'll use water between late November to late March. I'll install valves on the water distribution manifold to everything that way I can use water where needed without having to waste water draining the entire system again. This addition is purely for convenience and trying to keep some mess out of the house. |

Plumbing can be made a lot easier. Stack the washer and dryer, and use an instantaneous water heater mounted high on the wall. While I'm not crazy about instant hot water heaters, for a limited use space such as that, they're fine and will free up a lot of space, and can be gas or electric. Move things around and you should be able to fit a 60" shower in the space easily, or possibly an angled shower-properly configured, they have a lot of room. One of the things we did when planning our floor plan was to use cardboard boxes shaped and sized to represent things, i.e. washer, toilet, etc. That made it a lot easier to visualize, move around. and was better than guessing.

You got that right. I've been without a garage sink for eight years now. Once you've had one, it's tough to live without one.

It's an addition to not a built in. So no wasted shop space. It's at a premium until the big 30x40 shop gets built.
