Direct answer
An automatic pool cover is planned, not purchased: the track type, vault or bench location, drainage, and electric or hydraulic drive all occupy space inside the pool structure. Deciding them during design, before the shell is placed, makes the cover a clean line item; deciding them later makes it a demolition project.
Key takeaways
- Cover decisions are structural: track, vault, drainage, and power live inside the shell and coping.
- The five decisions to lock early are track type, vault geometry, drive type, drainage, and coping profile.
- A cover changes evaporation, heat loss, and safety behavior, so it also changes equipment and water planning.
- Everything agreed must appear on the construction drawings, not in a later change order.
An automatic cover bought late is an awkward retrofit. An automatic cover planned early is a set of small decisions made while they still cost little. That is why this page sits at the front of the pool covers hub rather than at the end of a catalog.
This page is the decision framework: the five choices and what each commits you to. When you need the same decisions mapped onto the build schedule stage by stage, continue to covers for new construction; for a pool that already exists, start from the retrofit guide instead.
The five decisions to lock during design
- Track type. Undertrack (concealed beneath the coping), top track (surface-mounted on the deck), or recessed deck tracks. The choice drives the coping profile and how visible the system is — the three families are compared in track types.
- Vault or bench. The roll of fabric and its drum live in a vault at one end, a bench housing, or a mechanism space behind the wall. Its dimensions are structural.
- Drive type. Electric motor or hydraulic power pack. Electric drives put a motor near the vault. Hydraulic systems put a small pump unit on the equipment pad and run hoses. The trade-offs are in hydraulic vs electric.
- Drainage. Vaults collect rain and splash-out. A vault drain that connects to real drainage is the single most commonly missed detail — the full wet-side design is in vaults, drainage and power.
- Coping and deck interface. The stone or concrete edge must match the chosen track before it is ordered, not after it is laid.
What a cover changes elsewhere in the plan
Evaporation is the largest heat and water loss from an open pool, and a cover cuts most of it. That shrinks heater duty and makeup water, and it matters double in the climates covered in pool design for hot climates. On the equipment side, the drive and a cover pump become rows on the equipment schedule, with pad space to match.
A cover also changes daily safety behavior, but a cover is a product with its own tested ratings. Check the specific model’s documentation rather than assuming any cover meets any standard.
Getting it onto the drawings
Every decision above has to appear on the construction documents. The construction sequence embeds them at the steel-and-plumbing stage. The automatic pool cover coordination checklist walks the full list (dimensions, track, vault, drainage, power, coping, and the drawing sign-off points) in a form you can hand to the builder.
What this page leaves out
Repair, fabric replacement, and troubleshooting are service topics for existing covers and are out of scope here. This site covers planning: getting the system into the structure on the first installation.
Frequently asked questions
When is the right time to decide on an automatic cover?
During design, at the same time as the pool's shape and equipment location. Track recesses, the vault, its drain, and the drive's power or hydraulic lines are embedded in the structure, so the decision deadline is the shell, the same deadline as plumbing and steel.
Does a rectangular pool make covers easier?
Yes. A true rectangle lets the cover track run parallel along both sides, in deck recesses or under coping. Freeform shapes need a track wider than the water at every point, which grows the system and the cost. If a cover matters to you, let it influence the shape early.
What does a cover change about the rest of the project?
Covered pools lose far less water and heat to evaporation, which affects heater sizing and makeup-water planning. The vault needs a drain that actually goes somewhere, the deck needs a coping profile matched to the track, and the equipment plan gains a drive unit and usually a cover pump.
