Turn the sticker price into a project range.

A planning estimate, not a contractor quote. Change every assumption; nothing is hidden.

Planning total

$9,534
Use a working range of $8,581–$10,487

Before buying, confirm circuit, clearances, ventilation, foundation, local permit rules, delivery access, and who owns warranty service after installation.

Evidence, without the wellness fog

Heat can feel good. Health claims need a higher bar.

This is educational context, not medical advice. Talk with a qualified clinician about personal risks.

Mixed · current RCT evidence

Longer-term cardiometabolic outcomes

Moderate to low certainty

Blood pressure and vascular function

A 2021 meta-analysis reported reductions in blood pressure after repeated heat therapy, while rating certainty moderate for some outcomes and low for others.

Limited · specific population

Infrared sauna and heart failure

A 2018 review found short-term changes in selected heart-failure measures, but only infrared studies met inclusion criteria and long-term evidence remained insufficient.

Basic safety

Heat exposure can increase heart rate and dehydration risk. Leave if you feel dizzy or unwell. People who are pregnant, have cardiovascular conditions, take medications affecting heat or blood pressure, or have other concerns should seek individualized medical guidance first.
