A garden tub, also known as a soaking tub, is a deep, freestanding bathtub designed for relaxation. Unlike standard tubs, garden tubs are typically wider and deeper, allowing you to submerge more of your body. They originated in Japanese and Scandinavian bathing cultures, where soaking in hot water is a ritual for stress relief. Today, garden tubs are a popular feature in master bathrooms, offering a spa-like experience at home.
What Defines a Garden Tub?
Garden tubs are characterized by their depth (usually 18-24 inches) and shape. They are often oval or rectangular, with a flat bottom and sloping sides. Most are made from acrylic, fiberglass, or cast iron. Unlike alcove tubs that fit into a three-wall enclosure, garden tubs are freestanding or drop-in. They don’t have jets like a whirlpool tub; the focus is on simple soaking. Key measurement: water depth should be at least 15 inches to cover your hips when seated.
Garden Tub vs. Soaking Tub: Is There a Difference?
In the US, the terms are often used interchangeably, but there’s a subtle distinction. A soaking tub is any deep tub meant for immersion, while a garden tub specifically refers to a freestanding tub that is not attached to a wall. Most garden tubs have a deck or rim that can be tiled or finished. Soaking tubs can be alcove or drop-in. Practical tip: if you want a standalone statement piece, choose a garden tub. If you need to fit into an existing alcove, look for a soaking tub with similar depth.
Pros and Cons of Installing a Garden Tub
Pros:
1. Deep immersion for relaxation.
2. Aesthetic appeal – creates a focal point.
3. Easy to clean (no corners or crevices).
4. Can increase home resale value if done tastefully.
Cons:
1. Requires more floor space (typically 60x30 inches or larger).
2. Higher cost: tub alone $800–$3,000, plus installation.
3. Water usage: up to 40-60 gallons per fill.
4. May need a reinforced floor for heavy tubs (especially cast iron).
How to Choose the Right Garden Tub: 5 Key Factors
1. Material: Acrylic is lightweight, warm to touch, and affordable. Fiberglass is cheaper but less durable. Cast iron retains heat well but is heavy (require floor support). Stone resin is a premium option with good heat retention.
2. Size and Shape: Measure your bathroom’s clear floor area. Allow at least 30 inches of walking space around the tub. Oval tubs are comfortable for two; rectangular fits tight spaces. Depth should be at least 18 inches for effective soaking.
3. Installation Type: Freestanding tubs need a floor-mounted faucet or wall-mount. Drop-in tubs require a deck built around them. Consider plumbing access – some freestanding tubs have pre-mounted faucets.
4. Drain Location: Center drain is standard. Offset drain may require special plumbing. Check if the tub comes with a drain kit.
5. Comfort Features: Look for sloped backrests, armrests, and a contoured interior. Some models include built-in lumbar support or headrests.
Installation Steps and Common Mistakes
Step-by-step installation (simplified):
1. Prep the floor – ensure it’s level and can support weight. For heavy tubs, add plywood subfloor.
2. Position the tub and mark drain location.
3. Connect drain and overflow pipes (use PVC or brass).
4. Secure the tub according to manufacturer instructions (some need mortar base).
5. Install faucet and handles.
6. Seal edges with silicone caulk.
Common mistakes:
- Not checking floor load capacity (especially for cast iron).
- Forgetting to insulate the tub for heat retention.
- Installing the faucet too low (should be at least 6 inches above rim).
- Using incorrect drain height – standard is 16-18 inches from floor.
FAQ About Garden Tubs
Q: Can a garden tub fit in a small bathroom?
A: Yes, but choose a smaller model (54x30 inches) and consider a corner placement. Ensure at least 24 inches of clearance in front.
Q: Is a garden tub hard to clean?
A: No, because there are no corners. Wipe with non-abrasive cleaner after each use. For acrylic, avoid harsh chemicals.
Q: Do garden tubs hold heat well?
A: Acrylic and fiberglass lose heat faster. Cast iron and stone resin retain heat longer. Use a tub cover to keep water warm.
Q: Can I add jets to a garden tub?
A: Some models are available with jets, but that’s a jetted tub. If you want both, look for a combo unit.
Final Buying Advice
A garden tub can transform your bathroom into a personal retreat. Focus on depth and material over brand. Test the tub’s comfort (if possible) by sitting in it at a showroom. Budget for installation – expect $500–$1,500 for plumbing and labor. For durability, choose acrylic or stone resin. Avoid cheap fiberglass models that may crack. Remember, a garden tub is about relaxation, not just bathing. Invest in a quality faucet and consider adding a tub filler for a luxurious touch.
