How Do RV Shower Toilet Combos Work?

Despite sharing the same space, showers and toilets in shower toilet combos don’t use the same drain. Usually, water from the showers would go through the drain that connects to the grey water tank. In case you don’t know, the grey water tank is also the destination of water that drops down the sinks. As for the toilets of shower toilet combos, water going through them should end up in the black water tank. 

Note: If your shower toilet combos integrate a cassette toilet, water is going to go to the cassette. With cassette toilets, you have to drain the cassette instead of the black water tank when the time comes.

  • Dry the unit after use: With all the water splashes, it’s wise to dry the shower toilet combo following each time you shower. By doing so, you could avoid a multitude of troubles from wet feet to water damage on the road. To dry a RV shower toilet combo, you should add a squeegee to your travel inventory to remove water from surfaces. Also, it’s strongly recommended that you place a rug with rubber back on the floor of the unit outside of use for protection.
  • Be wary of damages: A typical RV shower toilet sink combo isn’t prone to damage but it would break if exposed to too much abuse. Since using broken units increases the risk of water damages as time passes by, you must be vigilant. For minor damages, it’s a good idea to cover them in strips of Eternabond tape to keep water out. Nonetheless, if the extent of damages is extensive, play it safe and just replace the unit altogether. 
  • Designate a cabinet for toiletries: Many shower toilet combos for recreational vehicles come with integral storage for toilet paper but that is it. As a result, it’s convenient to have a cabinet dedicated to the storage of toiletries on your RV. Such a cabinet is going to let you prevent toiletries from getting while allowing you to access toiletries at a moment’s notice. You could set up the toiletry cabinet anywhere you like but for the ease of convenience, prioritize locations within the proximity of your shower toilet combination. 
  • Turn on the ventilation fan: moisture always accompanies water which is why shower toilet combos release a large amount of moisture into the surroundings when people use them. Hence, to stop moisture from accumulating in the interior of your RV,  keep the ventilation fan on during and after shower times. With the fan pulling out moisture, you don’t have to worry too much about moisture damages in the outdoors. For good measure, depending on the situation, you should open windows and doors of your rig to improve air circulation. 
  • Do the sudsy things first: Regarding the order of things to do in the shower, it’s all about individual liking. However, to facilitate drainage, it’s suggested that you do the sudsy things first before washing everything down with water.
