Stainless Steel | Ice Bath Tub

The Stainless Steel Ice Bath Tub is built for those who want their ice bath to last a lifetime. Constructed entirely from marine-grade 304/316 stainless steel — the same material used in boat fittings and coastal infrastructure — this tub won't rust, corrode, or degrade, regardless of how many years it spends outdoors in Thailand's humidity.

The double-wall construction traps a layer of high-density insulation between inner and outer shells, dramatically reducing heat transfer from the environment. Your chiller works less, your electricity bill stays lower, and your water stays colder longer between sessions.

Inside, the ergonomic profile supports your body in a natural recline, reducing pressure on your lower back during longer immersions. No awkward perching on a flat bottom — just settle in and breathe.

Installation

• 1. Position the unit on a flat, level surface near a power outlet
• 2. Ensure adequate ventilation around the unit for heat dissipation
• 3. Fill with clean water to the indicated line
• 4. Plug into a grounded 220V outlet
• 5. Power on and set the target temperature via the control panel or app
• 6. Allow 12-24 hours for initial cool-down to the target temperature
• 7. Fit an insulated cover when not in use
• Note: Unit requires approximately 50cm clearance on all sides for airflow. Indoor installation is recommended for optimal performance and longevity.

Ice Bath Care & Maintenance

• Your Sisu ice bath is built to last with minimal upkeep. A simple routine keeps the water fresh, the equipment running efficiently, and your cold plunge experience at its best. Whether you're using an integrated chiller system or adding ice manually, these steps will help you get the most out of your investment.
• The key to low-maintenance ownership is consistency. A few minutes after each session and a short weekly check prevents the kind of buildup that leads to bigger jobs down the track.

After Every Session

• Shower before entering. Body oils, sunscreen, sweat, and lotions are the number one cause of cloudy water and filter clogging. A quick rinse before you plunge makes a significant difference to water quality.
• Replace the insulated lid immediately. This maintains water temperature, reduces energy consumption on chiller units, and keeps debris, insects, and leaves out of the water.
• Wipe down the rim and any exposed surfaces with a clean cloth to prevent waterline buildup.
• Remove any visible debris from the water with a small skimmer net.

Weekly Routine

• Check water clarity and smell. Clean water should be clear with no odour. If cloudy or smelly, change the water regardless of when you last filled it.
• Clean or rinse the filter element (chiller models). Remove the cartridge and rinse under running water — takes under two minutes and keeps circulation at full flow.
• Wipe the waterline around the interior with a soft cloth or non-abrasive sponge. Mild dish soap or diluted white vinegar is all you need.
• Test water quality if you're using sanitising tablets or water treatment products. Simple test strips from pool supply shops give a quick read on pH and sanitiser levels.

Fortnightly (Chiller Models)

• Check the ozone generator is functioning. Most units have an indicator light — if it's off or flashing, consult your user manual or contact us.
• Inspect hose connections between the chiller and tub for leaks or loosening. Tighten fittings by hand — don't overtighten.
• Clean the chiller's air intake and exhaust vents. Dust and insects accumulate quickly in Thailand's climate. Wipe or vacuum the vents to maintain airflow and cooling efficiency.

Monthly Routine

• Deep clean the interior. Drain completely, wipe all interior surfaces with a mild cleaning solution, and rinse thoroughly before refilling. For stainless steel, use a dedicated stainless steel cleaner. For composite or timber, use only approved products for that material.
• Replace the filter cartridge if showing wear, discolouration, or reduced flow even after rinsing. Most filters last 2–3 months depending on usage.
• Inspect the drain valve and plug for signs of wear or slow leaking. Replace seals if needed.
• Timber exteriors: Check for cracking, splitting, or discolouration. Apply recommended timber treatment oil if the wood appears dry. Thailand's UV and humidity accelerate timber aging.

Water Change Schedule

• With chiller, ozone, and filtration: Change every 2–4 weeks depending on usage. Heavy daily use or multiple users requires more frequent changes.
• Without a chiller (manual ice): Change after every session, or at minimum every 2–3 days. Standing water without sanitation becomes a breeding ground for bacteria in Thailand's warm climate.
• Always use clean tap water. If your supply has high mineral content, consider a basic inline filter on your garden hose to reduce calcium buildup.

Seasonal Tips for Thailand

• Hot season (March–May): Expect longer cooling times and higher energy use. Ensure good ventilation around the chiller and keep it out of direct sunlight.
• Rainy season: Outdoor tubs need more frequent cleaning. Check for debris buildup and ensure the area around the base has adequate drainage.

What to Avoid

• No bleach, pool chlorine, or harsh chemicals. These damage interior surfaces, seals, and chiller components. Use products designed for small cold plunge systems, or ask us for recommendations.
• Never leave the tub uncovered. Uncovered water in Thailand attracts mosquitoes and debris rapidly.
• Don't run the chiller without adequate water level. The pump must be fully submerged. Running dry damages the pump and voids your warranty.
• Don't pressure wash timber exteriors. High pressure forces water into the grain and causes splitting. A gentle hose and wipe is sufficient.

Chiller Maintenance

• Keep the unit on a level, stable surface with at least 30cm clearance on all sides for airflow.
• Visually check refrigerant lines for damage or wear. Do not attempt refrigerant repairs yourself — contact us or a qualified technician.
• The compressor and fan are sealed units requiring no user maintenance. If you hear unusual noises, frequent cycling, or the unit isn't reaching target temperature, contact support.
• Clean the condenser coils every 3–6 months by gently brushing off dust and debris. This is the single most impactful task for chiller longevity and efficiency.

When to Contact Us

• Water not reaching target temperature despite clean filters and vents
• Unusual noises from the chiller or pump
• Error codes on the digital controller
• Ozone generator not activating
• Any leaks from the tub, fittings, or chiller unit
• Visible damage to the interior surface
• Questions about replacement parts or filter cartridges

Warranty Reminder

• Regular maintenance as outlined above is a condition of your warranty. Keep a simple log of water changes and filter replacements — this protects you in the unlikely event of a warranty claim and helps us diagnose issues faster.

**Q: Why stainless steel over wood or composite?

A: Longevity and hygiene. Stainless doesn't absorb bacteria, won't rot, and never needs sealing or treatment. It's the same reason commercial kitchens and hospitals use it. The initial cost is higher, the lifetime cost is lower.

**Q: Is 304 or 316 steel better?

A: 316 has added molybdenum for superior corrosion resistance, especially in salt or coastal environments. For most Thai locations, 304 is perfectly adequate. Both grades are included in this product's construction.

**Q: Will it get hot in the sun?

A: The exterior can warm up in direct sunlight, but the double-wall insulation prevents this from significantly affecting water temperature. A shaded location is still recommended for best performance.

**Q: Can I use salt or minerals in the water?

A: Yes. Marine-grade stainless is designed to resist salt corrosion. This is one of the key advantages over composite or timber tubs.

**Q: How do I clean stainless steel?

A: Wipe down with a soft cloth and mild detergent. For watermarks or fingerprints, use a stainless steel cleaner. Avoid abrasive pads that can scratch the brushed finish.

**Q: Which chiller should I pair with this?

A: 1.0 HP for home use with 1-2 daily sessions. 2.0 HP for commercial use, frequent sessions, or faster temperature recovery.

**Q: What's the warranty?

A: 2 years covering manufacturing defects, including weld integrity and material corrosion under normal use. Does not cover cosmetic scratches, improper installation, or damage from incompatible chemicals.
