Complete Bathtub Buying & Conversion Guide — Copper, 2-Person, Corner, Jets & Replacing with a Shower

Why choose the right bathtub (short guide)

Bathtub choice affects comfort, resale value and bathroom layout. Key decisions: size (single vs two-person), configuration (straight, corner, freestanding), material (copper, acrylic, cast iron), functionality (jets, air baths, integrated shower), and installation complexity. Below we break down the most searched keywords and practical buying and installation advice.

1. Copper bathtub with shower — pros, cons & care

Copper tubs are prized for their warmth, antimicrobial properties, and unique ageing (patina). A copper bathtub with shower pairs luxury with practicality when you need both soaking and quick rinsing.

Pros

• Beautiful, distinctive look — patinas over time for a one-of-a-kind finish.
• Excellent heat retention — water stays warmer longer for comfortable soaks.
• Natural antimicrobial properties thanks to copper.

Cons & considerations

• Higher cost than acrylic or steel; may require specialist plumbing and supports.
• Unlacquered copper will age; if you want a bright finish choose lacquered copper but it may need re-coating eventually.
• Surface care: avoid harsh abrasives and acidic cleaners — use mild soap and dry after use.

Installation notes

When combining a copper tub with a shower, specify a shower mixer and wall surround compatible with copper. Consider using a tiled or waterproof wall system (e.g., cement board + tile) and ensure the tub flange and shower screen/curtain prevent water ingress to the joint.

2. Bathtub for small bathroom — space-smart options and tips

Small bathrooms benefit from designs that maximise usable space without sacrificing comfort.

Top styles for small bathrooms

• Shorter-length tubs: Standard tubs are 1700–1800mm; compact tubs can be 1400–1500mm.
• Shallow soak tubs: Lower depth but comfortable for quick soaks and space savings.
• Corner tubs: Triangular or curved corner tubs free up wall space and can fit in tight layouts.
• Shower-over-tub combos: Great if you need both functions in a small footprint.

Layout & planning tips

1. Measure clearances — leave at least 600mm clear in front of the tub for access.
2. Consider a sliding or bi-fold shower screen instead of a swinging door for tight spaces.
3. Use light colours and vertical tiles to visually expand the room.

3. 2 person corner bathtub & bathtub for 2 person — design, sizes & jets

2 person corner bathtubs are designed to accommodate two adults comfortably and are often installed in master bathrooms or en-suites to add a luxury touch. These can be corner triangular or L-shaped, maximising floor space while offering a generous bathing area.

Typical sizes & shapes

• Corner two-person tubs usually start around 1500–1600mm on each wall face, and larger models reach 1750–1900mm.
• Freestanding two-person tubs may be 1700–1900mm length and 800–1000mm width.

2 person bathtub with jets — what to know

Hydrotherapy jets add a spa-like experience. Features to compare:

• Jet count and placement: Look for adjustable jets that can target back and shoulder areas for both occupants.
• Pump power: Higher CFM/pump rating equals stronger jet action — check manufacturer specifications.
• Air vs water jets: Water jets are stronger; air jets give gentler, effervescent massage.
• Cleaning cycles & access panels: Ensure the tub has accessible service panels and hygienic plumbing layouts to avoid bacterial buildup in piping.

2 person bathtub with shower

Many 2-person models can be specified with an integrated shower option — either via a tiled surround and shower mixer or with a dedicated shower screen. This is ideal when the same bathroom must serve as both a quick daily shower space and a luxury soaking area.

4. Choosing material — copper, acrylic, cast iron, stone & composites

Material affects look, weight, heat retention, cost and maintenance.

• Copper: Premium, warm, antimicrobial, patinas over time — artisan appeal.
• Acrylic: Lightweight, affordable, easy to shape — common for small and corner tubs.
• Cast iron: Extremely durable and retains heat well, but very heavy — requires reinforced floor.
• Solid surface / stone composites: High-end look, excellent thermal mass, can be heavy.

5. Plumbing, electrical & ventilation considerations

Two critical systems to plan for:

• Plumbing: Jets need dedicated pumps and usually a 2–3" drain. Confirm trap location and overflow positions. For corner and two-person tubs, ensure drain alignment with floor waste to avoid costly rework.
• Electrical: Hot tub pumps and air blowers require GFCI-protected circuits and must follow local electrical codes. Always use a licensed electrician for these connections.
• Ventilation: Adding a shower or installing a two-person tub in an enclosed space increases humidity — ensure an extractor fan with adequate airflow (measured in m³/hr) is installed.

6. How to replace bathtub with a shower — step-by-step (overview)

Converting a bathtub to a shower is a common remodel that opens up space and modernises bathrooms. Below is a practical step-by-step overview. This is a general guide — always check local building codes and, where required, hire a licensed tradesperson.

Preparation

1. Decide your shower layout: Use the existing tub alcove, or remove tub and extend shower area. Choose shower type: tiled wet-wall, pre-fab shower pan, or walk-in curbless.
2. Obtain permits: If your area requires permits for plumbing/electrical changes, get them before work begins.
3. Gather materials & tools: Demolition tools, plumbing fittings, shower pan or mortar bed, waterproofing membrane (e.g., wedi or cement board + membrane), tile/grout, shower door/screen, fixtures, and drainage components.

Demolition

1. Turn off water and power to the bathroom.
2. Remove faucet fixtures, showerhead, and trim plates.
3. Demolish bathtub carefully — cut away surrounding tile or wall cover as planned and disconnect drain/trap.
4. Remove the tub and clear debris — check floor framing for rot or damage.

Rough-in plumbing

1. Re-route drain if changing from tub to a different shower drain location — install a code-compliant shower drain and p-trap below floor level.
2. Install or relocate mixing valve at comfortable height (typically 42–48" above finished floor) and rough in supply lines.

Substrate & waterproofing

1. Install a shower pan (pre-formed) or build a mortar bed with waterproof liner for tiled showers.
2. Apply cement backer board (e.g., cement board) or an approved foam backer, seal seams, and apply a waterproofing membrane or liquid-applied membrane per manufacturer instructions.

Finish & fixtures

1. Tile or install wall panels; grout and seal as required.
2. Install shower fixtures (valve trim, showerhead) and door or fixed screen. Use silicone at joints where needed.
3. Test the shower: check for leaks, proper drain flow, and correct valve operation.

Final checks & ventilation

1. Ensure the exhaust fan is sized correctly for the room size and run it to remove moisture after showers.
2. Complete any painting and trim work.
3. Schedule a final inspection if permits were required.

Tip: If you want a low-disruption option, consider a pre-fab shower conversion kit or an acrylic shower base that fits the existing footprint — these reduce labor and can be completed faster than a full tile rebuild.

7. Accessibility & comfort features

Consider these if you want longevity, safety and comfort:

• Grab bars and non-slip surfaces for safety.
• Built-in seating or a bench — helpful for elderly or for shaving while showering.
• Thermostatic mixing valves to prevent scalding.
• Handheld showers in addition to overhead heads for flexibility.
