Home gym and private spa design

A loaded weight rack can transmit over 400 kg of point load to the slab. Residential wellness design starts with the structure, not the finish.

A well-designed home gym or spa shows in what you don't see: the slab that doesn't vibrate when a plate drops, the air that's renewed silently, the indoor pool enclosure that doesn't condense, and ironmongery that doesn't corrode from chlorine within two years.

We treat these spaces with the same technical rigour as a commercial facility, scaled to a home: load calculations, air renewal, humidity control and materials selected to resist chloramines and steam.

What has to be resolved before the finish

Load on the slab

A weight rack, free-weight platform or impact zone can exceed a standard residential slab's admissible load; it's checked with the structural engineer before the layout is defined.

Impact and vibration transmission

Raised technical flooring with a damping layer isolated from the structure so dropped weights aren't transmitted to the floors below.

Minimum clear height

1.90 m for cardio equipment, up to 2.40 m with hanging elements or an Olympic bar; this determines which floors of the project can house the gym.

Accessible raised flooring

To reach HVAC and dehumidification installations without breaking up the floor every time there's an issue.

Air, water and condensation

Air changes per hour

A residential gym needs 6 to 8 air changes per hour; a heated indoor pool needs dedicated dehumidification on top of ventilation.

Condensation in indoor pool enclosures

Thermally broken glazing and dew-point control so the enclosure doesn't condense onto the joinery or ceiling.

Chloramines and ironmongery

The chlorinated environment of a pool or spa attacks standard hardware and profiles; we specify marine-grade stainless steel or anodised aluminium suited to chlorinated atmospheres.

Finnish sauna vs. steam room

A dry sauna needs unvarnished timber cladding and ventilation different from a saturated-steam room; they don't share finish or installation specifications.

What the project includes

Structural feasibility study

Checking admissible load with the engineer and defining which areas can take a gym or spa without structural reinforcement.

Installations design

HVAC, dehumidification, water treatment and acoustics sized to the room's real use, not a generic standard.

Specification of resistant materials

Anti-slip wet-area flooring, chloramine-resistant wall coverings and joinery specified for saturated atmospheres.

Site management

Supervision of critical installations — waterproofing, dehumidification, acoustic insulation — which are very costly to fix if they fail later.

Indicative investment for the service

Design and site-management fees. Specialist installation costs (dehumidification, water treatment) are quoted with the technical supplier.

Frequently asked questions

Can any slab take a home gym?

No. It depends on the admissible load calculated in the original structural project; sometimes heavy equipment has to be relocated over a column or load-bearing wall.

Can a home gym be fully soundproofed in a flat?

Impact transmission can be reduced very significantly with an isolated raised floor, but eliminating it completely isn't realistic in an existing structure.

What maintenance does a heated indoor pool need?

Regular servicing of dehumidification and water treatment; without it, condensation appears within a year.

Sauna or steam room, which is better?

It depends on use: a dry sauna is easier to maintain and install; a steam room demands more exacting waterproofing and ventilation but offers a different experience.

How long does a private spa take to build?

Between 4 and 7 months from approved project, depending on whether it requires structural reinforcement or only finishes and installations work.

Do you work with the building's structural engineer?

Yes, it's a mandatory step before defining the final layout of any zone with high point loads.
