Icon 437 22-1/2" x 18-1/2" x 6" Bottom Drain Holding Tank

Great product and very easy to install

I really like that I don't have to install this under my bus conversion. It just fits right under the toilet. I thought I read that some people said that the outlet opening is 1.5 inches. Mine is definitely 3 inches. Haven't put it in yet but it just looks to be a quality product.

Perfect for skoolie. I raised the floor six inches then dripped this in. I cut one hole through the floor of the bus for drainage and one through the ceiling for venting.Things to note:The vent hole sits way to close to the flange. If you have a hand flush on the same side as the vent hole, it will likely block the flush handle. This happened to me, so i 90° directly out of the vent hole to the back corner of the bathroom and then I 90° up through the ceiling.

I picked this up for a "poor man's Sealand" toilet mod on our RV. It was perfect for the job. This one has a toilet flange and a vent fitting on the top and a standard black tank drain fitting on the bottom. It has a textured top, internal bracing, and thick walls. There is no flex at all. It comes in black, but painting it white made it look much better. It's one of our best mods and was fairly simple.

Purchased this to replace the recirculating toilet in my Trailmanor. Easy to install and only needed to move the existing drain pipe about 1.5 inches. Able to mount a low profile directly on top. Added trim around the tank and now I have a much better toilet in my camper.

I put this in a weekender horse trailer. It’s easy to install and is made of quality products.

Installed in my camper. was PERFECT and so much easier to setup than those big clunky ones.

Perfect for my cargo trailer conversion camper.Wish they offered larger one than this.
