Diving Pool Conversion in Flower Mound, TX
Flower Mound Pool Resurfacing handles diving pool conversion in Flower Mound, Texas: filling in part of a diving pool’s deep end to make it shallower, taking out the board and giving the pool a new finish. Once converted, it becomes what the International Swimming Pool and Spa Code calls a Type O nondiving pool, and the code doesn’t allow diving equipment on a Type O pool. Typical Dallas–Fort Worth figures for 2026 put making a deep end shallower at $4,000 to $7,000.

What the code says about diving depths
Diving water envelopes
The code sorts residential pools built for diving equipment into Types I to V. The smallest, Types I and II, need a minimum diving water envelope 6 feet deep at Point A and 7 feet 6 inches at Point B, Type V needs 8 feet 6 inches and 9 feet, and no negative construction tolerances are allowed on those figures. Flower Mound’s amendments make the envelope the code’s table or the diving equipment maker’s figures, whichever is greater.
Diving boards and their makers
A board goes in the deep area where it gets the minimum envelope, installed to the maker’s instructions, and the board maker must say which boards fit which pool types. Each board carries a permanent label with the maker’s name and address, its date of manufacture, the minimum diving envelope and the maximum weight. S.R. Smith, a diving board maker, warns that using a board on a pool of the wrong size may result in death or serious injury, and calls for concrete at least 6 inches thick around the board’s mounting jig.
Diving and shallow water
The safety appendix of the ANSI/APSP/ICC-5 2011 standard, which is informational rather than part of the standard, tells pool owners never to allow diving, jumping or sliding into shallow water and never to dive head first into water 5 feet deep or less. Where signs warn against shallow-water diving, it points to the ANSI Z535 series of safety-sign standards.

Shallow end and slope change
Under the 2021 code, a residential pool’s shallow end is at least 33 inches and no more than 4 feet deep at its shallowest point, and the ANSI/APSP/ICC-5 2011 standard gives the same 2 feet 9 inches minimum. The change from shallow to deep comes at least 33 inches below the design waterline and at least 6 feet from the start of the shallow end, the deep-end floor slopes no steeper than 1 in 3, and the walls stay within 11 degrees of vertical down to a transition point at least 33 inches below the waterline.
Ways out and the safety line
If the deep area stays more than 5 feet deep, the code asks for a way in and out there as well, with handholds allowed where an exit would be hazardous. Wherever the floor has a first slope break, a rope and float line crosses the pool 1 to 2 feet toward the shallow side, anchored to the wall, the coping or the deck.
Steps and ledges after the conversion
The code’s rule that keeps steps, ladders, underwater benches and other features outside the minimum diving water envelope is written for pools designed for diving. Ledge and step options are on the page about tanning ledge and pool step additions.

Permits and the new finish
The 2024 code the Town adopted says no permit is needed for replastering or resurfacing an existing pool or spa, but that sentence names nothing else. A conversion changes the pool’s depths, and the Town’s amended code requires a permit before anyone alters a pool, so confirm with Building Inspections before work starts. The conversion ends with a new interior finish; white and colored plaster are covered under pool replastering, and a conversion can be one part of wider pool remodeling with new tile and coping. In Timber Creek, built mostly before 1990 by the Town's parcel records, the Town marks 17 of its 18 residential subdivision records as carrying no HOA requirement, so the Town permit is the main review there.
Double Oak, where the median home was built in 1988 by 2020–2024 survey estimates, lists “Pools & Hot Tubs” and “Additions and Remodels” among the work that needs a Town permit, and our page on diving pool conversion in Double Oak covers that town. Flower Mound Pool Resurfacing will lay out the permit steps first.

Published Dallas and national figures, not our prices. A real price needs a site visit.
National figures from 2024 give the reason for the lower price: going shallower needs only draining, filling in and resurfacing, with no excavating.

(469) 526-3886Diving pool conversion questions and answers
How deep does a pool have to be to install a diving board?
Under the 2021 International Swimming Pool and Spa Code, the smallest residential diving types need a minimum diving water envelope 6 feet deep at Point A and 7 feet 6 inches at Point B, rising to 8 feet 6 inches and 9 feet for Type V. In Flower Mound the envelope is the code’s or the board maker’s, whichever is greater, and the board maker must say which pool types each board fits.
Can a diving pool be made shallower?
Yes. National figures from 2024 describe it as draining, filling in and resurfacing, with no excavating, and the converted pool becomes a Type O nondiving pool under the code, with a shallow end of 33 inches to 4 feet. Flower Mound Pool Resurfacing will talk through the new depths after seeing the pool.
Can I keep the diving board after a conversion?
No. The code doesn’t allow manufactured or fabricated diving equipment on a Type O nondiving pool, and a board has to sit where it gets the full minimum diving envelope.
How much does a diving pool conversion cost?
Dallas figures for 2026 put converting a pool from deep to shallow at $4,000 to $7,000, against $10,000 to $50,000 to go from shallow to deep. National figures from 2025 put making a deep pool shallow at $3,500 to $7,000.
Does a converted pool still need a safety rope?
Where the floor has a first slope break, the 2021 code asks for a rope and float line across the pool 1 to 2 feet toward the shallow side of the break. If the deep area stays deeper than 5 feet, it also needs its own way in and out.
