Merry Products Cat Washroom Bench - White Pet Grooming Station for Indoor Cats | Perfect for Bathing, Brushing & Nail Trimming at Home

This unit comes in 8 pieces: back, left side, right side, top, bottom, left door, right door, and optional divider. You will need a large phillips screwdriver and a small phillips screwdriver for assembly. I took me about 45 minutes to un-package and assemble it myself. It is held together with approximately 18 cam-bolt combos and an equal number of dowels for added strength. The cat door entry can be installed on either the left of right. Each door has two hinges installed on the door, but you must attach the other side of the hinges to the main unit as part of the assembly process using two small screws on each of the four hinges. Helpful hint: it is difficult to line up the door hinge holes with the screw holes in the unit when the door is loose – prop the door up in near-installed position using some of the styrofoam packing material so that the hinge holes are aligned with the unit’s screw holes, then screw in the small screws. I would not call this a “fine piece of furniture” like some other reviewers – I consider it decent, with some of the wood stain not fully applied in crevices, and a minor cosmetic surface issue (not shipping damage). Neither of these are major issues.Modifications:1) Pee-proof the interior (up to 8 inches in height) for about $25: others have complained that if your cat “misses,” urine will soak onto the wood and ruin the unit. Too bad they don’t offer a plastic interior liner to help protect from this. Here’s what I did instead: Purchase approximately 8 feet of plastic carpet runner (approx. 27 inches wide) at your local hardware store – not the clear type, the black plastic type for about $2.25 per linear foot. You’ll also need a 5 oz. tube of adhesive like Dap, a 3 oz. tube of silicone, a decent pair of scissors, and a tape measure. Step 1: cut a piece of the runner to the width of the interior floor, put in the base of the unit, align with the front base edge of the unit, and “fold up” the approx. 8-inch excess on the back wall of the unit, affix with adhesive - the floor and the rear wall are now protected. Step 2: cut a piece of runner the depth of the unit, and the height of the bottom of the cat entry door, and affix with adhesive – one side of the unit is now protected. Step 3: cut a piece of runner the depth of the unit, and 8 inches tall, and affix to the other side wall with adhesive – the other side of the unit is now protected. Protecting the front of the unit is more tricky - Step 4: cut a strip of runner the width of the unit, but only approx. 2inches tall – affix this strip vertically with adhesive to the ledge where the bottom of the doors touch the unit when they are closed – this will finish creating a “pan” for the interior that will catch and hold liquid. Step 5: seal all seams/gaps with Silicone: front, left, and right floor edges, and all four vertical edges. Not done yet – the front is only protected to a height of 1 or 2 inches – what if kitty pees on the inside of the doors? Step 6: cut two pieces of runner eight inches tall, one the width of the doors, the other 1 inch in excess of the width of the doors. These will line the interior of the doors to protect them, but the bottom of these runner pieces when installed must “stick out” (not be flush with the interior of the door) so that any liquid will be directed into the sealed pan” instead of the wooden gap between the pan and the door. Use a strip of wood of anything else handy and affix to the bottom rear of the runner pieces with adhesive to make them stick out when installed - affix the runner pieces to the inside of each door, with the sticking out portion just clearing the strip installed in Step 4. One runner piece will stick out 1 inch past the door edge – this is the door to close first to create an overlapping seal.2) Make the unit mobile for about $5. Purchase a 4-pack of 1 5/8 inch swivel bearing castors at your local hardware store. These are the types with pins instead of plates for installation. Remove the bottom four plastic feet from the unit (they are nailed in, so just pull them out with pliers). Follow the installation instructions for the wheels to install them where the plastic feet were removed – my set says to drill 3/8 inch holes 1 3/8 inches deep, tap in the provided sockets, then push casters into sockets until they lock. Rated caster load capacity of 50 pounds should be more than sufficient since the loaded unit should weigh about 100 pounds, which can be handled by 4 X 50 pound-rated casters = rated for 200 pounds (just don’t let people sit on the unit).
