Factors to consider

When deciding on the best unit to add to your ride for a trip, here are factors to consider when buying a macerator toilet. They will ensure that you get the best model for yourself, allowing you to get more value for the money you’re spending.
Toilet seat
Anti-bacterial toilet seats are something you should consider if you want to maintain proper hygiene while on the road. Some toilet seats also come with child locks, which are ideal if you’re traveling with kids.
Flush mechanism
A quiet flushing mechanism is necessary for busy households, but you might not need one for your boat. However, some camping spaces have strict rules about noise levels, which is something to consider if you’re getting a toilet for your RV.
Motor power rating
This rating can range from 250 to 600W. The greater the power rating, the more powerful and quiet the motor. The efficiency of your toilet increases with its power, as you won’t have to double flush.
