Concrete Bathtub Ideas: Natural Look! Unique & Personalized Bathtubs

Concrete bathtubs offer a unique look that brings a touch of nature into the bathroom. Their solid, sculptural forms and raw, organic texture provide a nice contrast to sleek porcelain or acrylic tubs. Concrete tubs come in a wide range of styles, from minimalist modern forms to more ornate vintage reproductions. The material is very versatile, allowing for personalized shapes, colors, and finishes. Read on to explore the many possibilities with concrete bathtub ideas for a natural, earthy look that feels refreshingly different.

Benefits of Concrete Bathtubs

Concrete bathtubs provide a number of advantages that make them a top choice for many homeowners:

  • Natural, organic look: The raw, mottled texture of concrete gives it an earthy, imperfect beauty reminiscent of stone or weathered wood. This provides a nice contrast to the perfect smoothness of acrylic or porcelain.
  • Versatility: Concrete can be molded into any shape and form, allowing for rounded, curvaceous, or geometric tubs. The material takes color easily, so tubs can be tinted or painted in any hue.
  • Durability: Properly treated and sealed concrete is extremely long-lasting and more scratch-resistant than some materials. With proper care, concrete tubs can last for decades.
  • Affordability: Concrete is generally more affordable than materials like stone or copper, while providing a similar natural, organic look.
  • Custom options: Concrete allows for unlimited customization in shape, color, size, even incorporated features like seats or shelves. This allows for a completely personalized bathtub.

So for those desiring a bathtub with rustic charm and unique style concrete is an excellent choice! Keep reading for plenty of design ideas.

Minimalist Modern Concrete Tub Designs

For a sleek, contemporary look, a simple monolithic slab of concrete makes a bold style statement. Unadorned rectangular forms work well in modern bathrooms where you want clean, crisp lines.

Rectangular Soaking Tub

A rectangular tub with straight sides provides a sculptural, minimalist look. For a serene spa-like vibe, choose a tub that allows for a deep soak. This creates an indulgent retreat right at home. Keep the drain simple and contemporarily styled.

Angled Back Rest

Adding a slight incline to one end of the tub creates an angled backrest for comfort and support. The asymmetry makes for a dynamically modern design. Keep lines very simple for maximum impact.

Curved End

A rectangular tub with one rounded end adds subtle interest while maintaining clean lines. The contrast between the circle and square shapes makes for a bold, geometric focal point.

Textural Interest

Playing with varied textures and finishes gives visual depth and dimension. Try a smooth interior with heavily sandblasted exterior or combine glossy and matte sections.

Soaking Shelf

Incorporate a wide, shallow integral shelf for placing bath accessories. This also conveniently provides an area for resting arms while soaking. Keep the shelf streamlined and minimalist.

Built-In Look

For a sleek custom look, consider attaching surrounding walls and ledges made of wood, tile, or cement board. This makes the tub appear to be part of a unified whole rather than a separate element.

Rounded Concrete Bathtub Styles

The fluid curves of rounded concrete tubs make them an enticing option. The organic shapes feel inviting, allowing you to sink in and relax.

Oval Tub

A simple oval form makes an elegant focal point, especially when placed on a diagonal in the room’s layout. An oval tub can fit in a variety of spaces while providing ample room for soaking.

Freeform Shape

Go bold with an entirely custom freeform tub created just for your space. Work with a professional to design a seamlessly integrated look tailored exactly for you.

Accent Arch

Incorporate an arch detail on one end of an oval tub for added visual interest and a touch of sophistication. This lends a subtle vintage vibe.

Molded Backrest

Maximize comfort with a molded-in backrest on one end of the tub. Gently curved for ergonomic support, this feels ultra-luxurious when reclining in a deep soak.

Curved Bench

Add integral seating with a curved bench or platform molded right into one side. Great for relaxation or conveniently resting feet and legs while bathing.

Rounded Corners

Soften the look of a rectangular tub by rounding the corners. The curved edges create a more organic, inviting shape while still allowing you to recline fully.

Ornate & Vintage Concrete Tub Designs

Concrete is easily molded into more elaborate, decorative styles for a touch of vintage luxury. These ornate tubs evoke a classic, romantic feel.

Clawfoot Tub

Perched atop clawfoot legs, these tubs have all the presence of cast iron or porcelain versions but with concrete’s earthy appeal. Extra luxurious with soaking depth.

Scroll Feet

For a more delicate look, try slender turned feet with scrolling motifs. This vintage detailing looks elegant on a simple tub shape.

Elevated Back

An exaggeratedly curved or slanted back creates a beautiful silhouette. Tailor the specific shape to your taste – the additional height provides comfortable lounging.

Double Slipper Tub

An oversized slipper tub design easily allows two people to enjoy a relaxing soak together. Make an indulgent statement in your master bath.

Scalloped Rim

Applied trim along the tub’s top edge lends ornate detail. Try repeating scallops, curved profiles, or bookend-style molding for a touch of whimsy.

Lion Feet

Incorporate figural elements like lion paw feet for vintage flair. Keep the tub shape clean to spotlight these artistic details.

Unique Add-Ons & Special Features

Part of the beauty of concrete tubs is how easily they can be customized. Take them to the next level with special add-ons tailored to your needs.

Integral Seating

Molded-in benches or platforms allow you to sit and relax in the tub. Positioning them at different depths and heights creates versatility.

Shelves & Trays

Incorporate ledges for keeping bath accessories within arm’s reach. Try different shapes and placement for handy storage solutions.

Surround the tub with built-in greenery by incorporating planter boxes and plant shelves right into the design. This brings the outdoors in!

Steps & Risers

Make it easy and safe to get in and out of a deep tub with integrated steps or risers at the head end. Tailor heights for comfort.

Grab Bars

Unobtrusive yet helpful grab bars can be set into the tub design for accessibility and stability getting in and out. Choose horizontal or angled bars.

Adjustable Drain

Rather than one fixed drain, incorporate a special adjustable drainage system. This allows you to customize the depth of your soak.

Embedded Objects

Make a tub truly one-of-a-kind by embedding found objects, marbles, sea glass, stones or personal treasures into the concrete as decoration.

Stylish Color Options

One of concrete’s assets is how readily it takes color for a completely custom look. Tinting or painting the concrete allows for any color tub you can dream up!

Warm Earth Tones

The natural gray color of concrete pairs beautifully with earthy hues like tan, brown and terra cotta. This enhances the material’s organic vibe.

Bold Brights

Make a dramatic splash by tinting or painting the concrete a vibrant hue like cherry red, cobalt blue, or even glossy black.

Soft Pastels

For a more soothing ambiance, use pale tints like baby blue, mauve, butter yellow or seafoam green. Surprisingly chic and elegant!

Patina Finish

The look of aged metal can be mimicked with a verdigris patina tint. This vintage greenish blue effect is eye-catching.

Ombre Color

Using graduated color – darker at one end fading lighter on the other – gives dynamic, unexpected flair. Layer translucent tints.

Speckled Tone

Mixing flecks of color into the concrete gives a beautifully mottled, speckled finish. Inspired by natural stone and aggregates.

Unique Bathtub Shapes to Consider

Nestle a simple concrete tub amidst plantings on a patio or deck. Choose lighter, natural hues that blend with the environment.

Rustic Woodsurround

Surround an outdoor tub with unstained wood planks for a cozy, countryside vibe. The rich texture complements weathered concrete.

Maintaining & Protecting Concrete Bathtubs

While very durable, concrete does require some protective measures to keep it looking its best and prevent damage. Here are tips for maintaining and sealing your concrete tub:

  • Allow new concrete to cure fully – generally about 4 weeks. This ensures it hardens completely before use.
  • Seal concrete with a penetrating concrete sealer to prevent staining and damage from moisture. Reapply yearly.
  • Avoid harsh cleaners like bleach. Use mild soap and water for routine cleaning.
  • Check for scratches or cracks in the sealer, reapplying to any problem spots as needed. This prevents water permeating the concrete.
  • Consider re-sanding and re-sealing the entire interior surface every 2-3 years to maintain the protective barrier.
  • Don’t let water pool for extended periods, drying fully between uses. This prevents long-term moisture damage.
  • For outdoor installations, check that drainage and freeze/thaw conditions won’t compromise the tub in colder climates.

With proper installation and care, a concrete bathtub can provide many years of enjoyment with their natural, earthy appeal!
