The K-3940-96 has quite a unique style. It gives off a modern vibe with its one piece frame, smooth edges, and tank shape. Lets take a look at the main specs below.

Its bowl provides chair height seating for user comfort and access purposes. It's also compliant with ADA criteria. Externally, the smoother edges conceal the trapway, which is perfect for cleaning as there is less corners and cracks for dirt, dust, and germs to gather.

If efficiency is something you want to improve upon in your bathroom, then this is certainly an option. It utilizes 1.28 gallons of water in each flush, with a gravity fed, AquaPiston system that will handle bulk waste effectively as well as clean the inside of the bowl from all angles.

This will come as a welcome addition to family homes. Eco and environmentally friendly, easy to clean, and low chances of it clogging up.

Considerations before you buy

Even if you've got your heart set on this particular product range, there are still some things that need to be considered before you decide to buy. We look at several important features underneath that should be thought about. Going through this short checklist will reduce the chances of you making common first time buyer mistakes.

Rough in distance - An essential part of your research should involve measuring your rough in. Not doing so can result in you having a poorly fitting toilet or worst still, something that doesn't fit at all. Save yourself from the replacement headaches by ensuring you do your research before hand. Twelve, fourteen, and ten inch rough ins are usually the three that most households require, but twelve is often seen as the industry standard size.

Outlet location - How you want your loo to handle waste after use should be on your mind. This doesn't usually come down to user preference unless you would be willing to completely overhaul the current plumbing set up. The two options you're usually presented with are floor based, or back flushing outlets.

Smart budgeting - This collection is arguably quite expensive when you compare residential toilets. However, what's expensive to one person, may be affordable to another. The sensible way forward in this respect is to set a budget before you even begin shopping. This will help prevent overspending. However, watch out for add ons and extras that manufacturers include such as separate seats and water supply lines.

Wrapping up
