Litter pans are a problem. Especially when you have a large cat who can't fit in a small litter box and a dog who considers cat poop a delicacy. It's been a struggle to find a commercial litter box the cat can enter and the dog can't.
On average, the cost to have an above ground pool deck professionally installed can range anywhere from $2,500 to as much as $8,000. The costs really come down to the type of material being used, the size of the pool, the design and contractor building the deck.
Cost: You could snag a set and fill pool for $100 and not need professional help, but it may last just a few summers. You can also get an above-ground pool with a wraparound deck for $10,000 or more. Costhelper.com lists prices for above-ground pools ranging from $1,500 to $5,000.
