Stinky tanks might need the popular “TubShroom®”

By Tony Barthel
One of the ways to keep your gray tank from becoming smelly is to minimize food waste that gets into it. Recently someone recommended using a TubShroom® to keep things from going down the drain. This actually seems like a good idea.

The TubShroom has been getting a lot of traction in advertisements on social media. It’s a handy device that pops into your drain and keeps hair and food waste from going down it. There are various models depending on the size of the drain, including ones for the shower and bathroom sink plus a Kitchen SinkShroom® as well. 

While I don’t have this device, we do have fine mesh screens on all our drains both in our proper house and in our RV. Since installing them we’ve had far fewer issues with clogs, which is a bonus. But the Kitchen SinkShroom is magic for the RV. It prevents food waste from heading down the drain and creating a smell in the tank. 

Installing these couldn’t be easier. You simply stick them in the drains in the tub and shower and over the large drain in the kitchen sink. Done. 

I did have to remove the stopper as our RV’s shower had one to stop water flow if we wanted to use the bathtub as a bathtub. There was also a stopper in the bathroom sink that just pulled out as well. The SinkShroom can also act as a stopper. 

If you’ve noticed your gray tank smelling, perhaps one of these might be a good investment. As an alternative, a fine mesh screen available at most hardware stores could also be the solution.

Yes wiping off the dishes with your napkin was the solution, and its saving a bunch of water, only need 1/2 the water as before, easier to clean dishes so its a win, win all the way around. Have not had any stink in gray tank now for 5 years.

We bought one for our RV shower after reading about this in one of your newsletters. Works like a charm and no more comments about my hair clogging the drain. 😉

At home we are on a septic system or on the road we always wipe off plates, dishes, and etc with our napkins before putting them in the sink. We also use a very fine mesh basket from the large home improvement box stores to catch everything else including most of the coffee grinds that gets past or around the filter.

I use the Tubshroom at home and RV. For my kitchen at home (septic) and RV I like this screen catcher, it’s a finer mesh and catches more debris:

I use these fine mesh strainers at home and in our motor home.

As with most of these “debris strainers”, the holes are too big. Coffee grounds and assorted small debris go right through.
