DB Trimax Questions

How deep are DB Trimax pools?

Every kit starts with a 3′-4″ shallow end. The 12′ × 24′ and 14′ × 28′ go to a 6′ deep end hopper; the 16′ × 32′, 18′ × 36′ and 20′ × 40′ go to 8′ (the 16′ × 32′ with the Full Width Step with 6′ Sunledge is 6′ deep, to fit the step). You can also choose a 3′-4″ flat bottom.

What comes in a kit?

The 42″ steel wall structure, coping, a vinyl liner in your pattern, your step, a handrail, a deep end ladder, a rope kit, 1 skimmer, 2 main drains and 3 returns. You can change the skimmer, main drain and return kit, and add a pump and filter, chlorinator, plumbing kit or LED light.

Which step should I choose?

The Full Width Step, the Full Width Step with 6′ Sunledge and the Corner Step with Full Width Bench are steel steps covered by your liner. The 8′ fiberglass step comes in Bullnose or Cantilever, in white, blue or grey. Each size and step has its own spec sheet.

Which coping should I choose?

CP2 Bullnose coping (white or grey) is for a poured concrete deck. Flat Track Cantilever coping is for a cantilevered concrete edge, pavers or stone. With the 8′ Cantilever fiberglass step, the coping is Flat Track Cantilever.

How long does shipping take?

DB Trimax kits ship within 7–10 business days.

Can I install it myself?

Yes. DB Trimax kits are made for DIY installation. Many DIYers hire out the excavation and the concrete footer, and handle the rest themselves. Installation isn’t included in the price of the kit.

Can a dealer install it?

A very select few participating Doughboy dealers install DB Trimax pools. Email us and we’ll check whether there’s one near you.

Do I need a permit or a fence?

Yes. Permits and fencing are always required for inground swimming pools: check your local code requirements and permitting office. Every DB Trimax pool ships with a Safety Packet, and the No Diving and other warning signs must be installed as the instructions show. See our pool safety guidelines.

DB Trimax or Hydrosphere: what’s the difference?

DB Trimax is a true inground pool with 42″ steel walls and a deep end, in a rectangle. The Hydrosphere Series has 52″ walls and a flat bottom, installs anywhere from 24″ semi-inground to fully inground, and comes in five shapes.
