A copper Japanese soaking tub can make a compact bathroom feel like a place to slow down, but the details matter: size, drain setup, overflow, and interior shape all affect whether it fits your space and bathing style. These three options include two freestanding Signature Hardware tubs and a hammered oval model from Premier Copper Products. Compare their listed features, then confirm the exact dimensions and installation needs before you buy.

Our Picks: Best Copper Japanese Soaking Tub reviews
Best for a Larger Bathing Area: Signature Hardware Raksha 60-Inch Tub
The 60-inch Raksha is the largest tub in this group. Its freestanding design gives it a distinct presence, while the 14-gauge copper construction is a specific material detail worth comparing with the other models. The tub is designed for soaking, and its center drain placement keeps the drain at the midpoint.
This model includes a pop-up drain assembly and overflow, so those components are part of the listed package. That can simplify planning compared with options that require a separate drain assembly. Still, check the full product specifications and your plumber’s requirements before ordering; the supplied details do not give the tub’s width, depth, or filled capacity.
The 60-inch length makes this the logical pick if you have enough floor space and want the longest option here. The trade-off is that it may be a poor fit for a smaller bathroom. Signature Hardware lists a 25-year limited warranty, but you should read its terms to understand coverage and exclusions.
Pros:
- Longest listed tub in this comparison at 60 inches
- Constructed of 14-gauge copper
- Includes a pop-up drain assembly and overflow
- Covered by a listed 25-year limited warranty
Cons:
- Requires more lengthwise space than the 48-inch options
- Width, depth, and capacity are not included in the supplied details
Verdict: Choose the 60-inch Raksha if you have room for a longer freestanding tub and want the drain assembly and overflow included.
Best Compact Freestanding Option: Signature Hardware Raksha 48-Inch Tub
This 48-inch Raksha keeps the freestanding copper design in a shorter format than the 60-inch model. It may be easier to plan around in a tighter room, although length alone does not determine fit: check the complete dimensions, faucet position, and access for installation before making a decision.
The tub has an integrated overflow and reversible drain placement. Those details give you flexibility when laying out the plumbing, but the drain assembly is not included. Allow for that separate component in your installation plan, and confirm that the drain you choose is compatible with the tub.
Like the larger Raksha, this model is covered by Signature Hardware’s listed 25-year limited warranty. The supplied product information identifies the material as copper but does not specify its gauge, so shoppers who want to compare copper thickness should verify that detail directly before purchase.
Pros:
- Shorter 48-inch length than the other Raksha option
- Integrated overflow
- Reversible drain placement offers layout flexibility
- Covered by a listed 25-year limited warranty
Cons:
- Drain assembly is not included
- Copper gauge is not specified in the supplied details
Verdict: Pick this Raksha if you want a shorter freestanding copper tub with an overflow and can source a compatible drain assembly separately.
Best Hammered Oval Design: Premier Copper Products 48-Inch Tub
Premier Copper Products takes a different approach with this 48-inch oval tub. Its listed features include a hammered copper surface and a seat, giving it a distinct shape and built-in place to sit. It is made from 16-gauge copper, compared with the 14-gauge construction specified for the 60-inch Raksha.
The drain opening is centered and measures 2 inches. This tub does not have an overflow, so make sure that setup suits your bathroom and your preferred installation. Its listed floor height is 3 to 4 inches from the ground; confirm how that measurement relates to your planned floor and plumbing before ordering.
This is the only model in the group that explicitly lists a seat and hammered finish. Those features may make it appealing if you prefer an oval shape and a more textured look. However, the supplied details do not list a drain assembly, so verify what is included and what you will need to buy separately.
Pros:
- Hammered copper surface gives it a distinct finish
- Includes a seat, according to the product description
- Centered 2-inch drain opening
- Listed 16-gauge copper construction
Cons:
- No overflow
- Drain assembly inclusion is not specified in the supplied details
Verdict: Choose the Premier Copper Products tub if an oval shape, hammered finish, and seat matter more to you than having an overflow.
How to Choose a Copper Japanese Soaking Tub
Measure the Room and the Tub’s Full Footprint
Start with the space where the tub will sit, not just the listed length. Measure the floor area and check the tub’s full width, height, and any clearance needed around it. The available product details list lengths but do not provide complete dimensions for every model, so confirm the manufacturer’s specifications before you plan the layout.
Think About the Interior Shape and Seating
A tub’s outer length does not tell you how much room you will have inside. Check the interior dimensions and bathing depth to see whether the tub suits your height and preferred soaking position. The Premier model specifically lists a seat; the supplied descriptions for the Raksha tubs do not list one.
Choose an Overflow Setup That Fits Your Plans
The two Signature Hardware options list overflow features: the 60-inch model includes an overflow drain, and the 48-inch model has an integrated overflow. The Premier tub is listed without an overflow. Consider your preferred plumbing setup and ask your installer whether the selected configuration works for your bathroom.
Confirm the Drain Location and Included Parts
Drain position affects plumbing placement. The 60-inch Raksha has a center drain and includes a pop-up drain assembly. The 48-inch Raksha has reversible drain placement but does not include a drain assembly. The Premier tub has a centered 2-inch drain opening; its supplied details do not say whether a drain assembly is included. Confirm compatibility and included parts before buying.
Compare Copper Construction and Finish
The 60-inch Raksha is specified as 14-gauge copper, while the Premier tub is specified as 16-gauge copper. The 48-inch Raksha description identifies copper but does not give a gauge. The Premier also has a hammered surface. These details help you compare the listed construction and appearance, but they do not replace checking the full product information and care instructions.
Plan for Installation and Bathing Needs
A freestanding tub still needs suitable plumbing, a stable floor, and a practical path into the bathroom. Before ordering, check the tub’s filled weight, installation instructions, faucet requirements, and any access restrictions with a qualified installer. These details are not provided in the product data here, so do not rely on length alone to decide whether a tub will work in your home.
Read Warranty and Care Information
Signature Hardware lists a 25-year limited warranty for both Raksha tubs. Review the warranty terms to understand what is covered and what steps may be required. For any copper tub, follow the maker’s care instructions and confirm which cleaning products are suitable for its specific finish.
Frequently Asked Questions
Which tub is the longest?
The Signature Hardware Raksha freestanding tub is listed at 60 inches. The other two options are listed at 48 inches.

Which tub has a seat?
The Premier Copper Products 48-inch oval tub is the only option in this comparison whose supplied description specifically lists a seat.
What is the difference between 14-gauge and 16-gauge copper here?
The 60-inch Raksha is listed as 14-gauge copper, while the Premier tub is listed as 16-gauge copper. The supplied information does not specify a gauge for the 48-inch Raksha. Compare the full manufacturer specifications if copper gauge is a key factor for you.

Final Recommendation
The Signature Hardware Raksha 60-inch tub is the strongest fit if you want the longest listed option with a center drain, included pop-up drain assembly, and overflow. For a shorter freestanding tub with an overflow, consider the 48-inch Raksha, while keeping in mind that its drain assembly is separate. Choose the Premier Copper Products model if its hammered oval design and listed seat suit your preferences and a no-overflow setup works for your installation. In every case, confirm the full specifications with the seller and your installer before ordering.
