The TOTO DuoFit In-Wall Tank Dual-Flush System with Copper Supply takes up less floor space, giving your bathroom a more open feel and making it easier to clean. The toilet mounting height is adjustable from 15 to 19 inches and can support up to 880 pounds. This modern design uses TOTO's Dual-Max® flushing system, allowing you to proactively conserve water with a full or light flush option. Choose between a 0.9 GPF rinse or 1.28 GPF for tougher jobs. The DUOFIT® harness allows you to select a mounting height of 15 to 19 inches. This provides the opportunity for you to establish a comfortable bowl height for a wide array of individuals. The in-wall unit can support up to 880lbs when installed properly. The kit arrives ready to be installed within a 2” x 6” stud setting with a 2" x 6" polyethylene waste outlet. If you require installation within a 2” x 4” setting, you will need to additionally purchase TOTO’s 2” x 4” PVC outlet kit (THU343). To enhance the installation with a WASHLET®® bidet seat, there is a pre-attached copper supply built into the system. The separately sold TOTO WASHLET® Connection kit will complete your WASHLET® install (THU468). This DUOFIT® requires the toilet bowl and flush push plate to be purchased separately.

Soft, comfortable looking. Not binding on toes. Not sure about “grippers “.
Style: 2 Pairs, Color: Non Slip Stone
New purchase for my 97 year old mom with multiple foot and ambulating issues.
Very soft, fit is okay, stretchy , enough toe room. I am not sure if the “grippers” will be adequate yet.
I am keeping this purchase and will wait to decide if the grippers will be adequate enough to help her ambulate and stand before I purchase more.

Perfect sleep socks!
Style: 1 Pair, Color: Stone Cloud
These sleep socks are so soft and comfy. They are perfect for cool weather (and are long enough to tuck in pajamas bottoms). I’m ordering more!

great addition to bedroom decor, soft and lux
Color: Tie-dye Sage, Size: Throw(50"x60")
I purchased this for my daughter for a gift. The softness Is next level.. The quality is greater than I expected and feels lux. It's thick without being too hot. It's a beautiful addition to their bedroom decor. It had no weird smell or order, and fit just as described. Ive washed a couple times and its holding up great.

Soft and cozy
Color: Tie-dye Cream Beige, Size: Twin(60"x80")
Recieved last week. The texture is soft and warm. Love it so far. The beige color is a little more greige than I expected but it still goes well with my decor.
