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.
On average, an in-ground pool can cost anything from $12,000 to $50,000. An above-ground pool may be a bit cheaper. But, if you want to add more features such as waterfalls, lights, attached spa, upgraded filtration and sanitizing equipment, concrete, etc., it may cost a lot more!
