K-6368-0 Sunstruck - A beautifully designed, oval shaped tub provides consumers with a unique option to use as the centrepiece in their washroom.

It's freestanding and comes in either biscuit or white colors. What's more, it has an impressive depth measurement of seventeen inches which is effectively a full body soak. So if you're looking for a deep model, this could be a good fit.

The bottom is textured for friction and grip, and the ends are deliberately designed to have slopes at each end for the sole pupose of back support and comfort. Also, the fact that there is very little gaps and is skirted ensure cleaning is a very simple task.

However, despite all the positives, there is a trade off. This is quite an expensive option. But if budget isn't an issue, this is certainly one to consider.

K-1118-LA-0 Expanse - This is a curved alcove tub from the Expanse range. It includes an integral apron and water protection in the form of tile flanges on each of its walled sides.

The bottom is textured for grip to prevent slippage whilst soaking, and the three walled design makes it a smart choice for consumers looking to save space in a compact washroom environment.

It's made from acrylic for durability, and at seventy pounds it's relatively light and easy to move around compared to some of its competitors.

K-1130-0 Underscore - This is a product which can be utilized in both undermount and drop in installations. It measures 60 inches in length by 32 inches in width by 21 inches in height and includes a slotted overflow at the end for safety measures.

This is made from acrylic and fiberglass which gives it strength and it is finished in white to help keep the washroom theme bright.

It can hold up to sixty gallons of water which combined with the length and width gives it a decent depth of twenty one inches.
