An 18x36 pool deck runs 648 square feet, the size that gives a rectangular pool a real walkway on every side plus a corner for chairs. It is a common upsize from 16x32 once a customer starts picturing furniture, and the extra footage changes the number in a predictable way.
Example rates, worked out
| Finish | Example rate | 18x36 (648 sq ft) |
|---|---|---|
| Broom texture | $9 / sq ft | $5,832 |
| Exposed aggregate | $13 / sq ft | $8,424 |
Example rates only, the way every page on this site shows them. The whole point of PriceDesk is that you swap in your own number instead of borrowing one off the internet.
What the extra footage carries
The add-ons scale with the area. Sealing at the example $2 per square foot is $1,296 on 648 feet, and it does more work here than on an interior slab because of sun, chemicals, and standing water. If the deck sits on fill or freezes in winter, reinforcement at $1.50 per square foot adds $972.
The design cost that is easy to underquote is the perimeter. More edge means more forming, more coping detail, and more control joints, so an 18x36 is not just a 16x32 with a flat markup.
Run your own pool size
The pool deck concrete calculator opens at 18x36 and reruns instantly for the 16x32 version or any freeform shape you break into rectangles. For the grip-finish upcharge, the stamped concrete cost calculator shows what a textured stamp does to the same footprint. And if the customer is weighing pavers instead, concrete pool deck vs pavers covers that fork.
