New Toilet

It is so nice to have this unit in my shop. I cannot add another water flush toilet to my property so this unit is working out great for shop use. However even as I explained to all that visits my shop and uses the toilet that they need to sit down to use it some still haven't creating a mess by standing to pee. That is when I found out the biodegradable bags leak when exposed to too much moisture and that the 6 gallon size bags do not fit very well. I have installed signs advising people to sit to use.
