Table of Contents

Small bathroom remodeling can be a massive undertaking, so it’s crucial to have a plan and a clear idea of the costs involved. From installing new fixtures and windows to using light colors or glass shower doors, there are many ideas to consider as you embark on the remodel. Depending on the materials, brand, and area, it might cost you between $5,500 and $15,000.

Why Small Bathrooms Pose Unique Challenges in Design and Functionality

The first step in undertaking a small bathroom remodeling project is to understand the unique challenges it presents. The most apparent yet significant challenge is the limited space available. Tight quarters make it a struggle to move around comfortably, impacting the bathroom’s functionality. 

Besides space constraints, limited light, ventilation, and storage also complicate the design process. Adjusting to the constraints and planning an aesthetically pleasing yet functional layout requires careful consideration.   

High-Impact Small Bathroom Remodeling Ideas for 2025

Limited space often presents design and functional challenges but opens the door to creativity. Whether there’s a compact nook or a tight corner, a well-thought-out plan can transform your bathroom in a way you enjoy. Here are some of the small bathroom remodeling ideas you can consider: 

Space-Enhancing Layout Adjustments: Understand how you and others in your household move within the available bathroom space. Accordingly, keep the sink, toilet, and shower placement for a smooth traffic flow. If there’s enough space, follow the “three-foot rule.” It involves maintaining three feet of open space in front of the fixtures. If you can’t accommodate that, keep the space to access the most frequently used area clean and uncluttered.

You can also keep the door swing outside, a well-designated area to store your toiletries, and invest in multifunctional furniture. 

Vertical Space Utilization: In a small bathroom, every inch counts. So, you must be smart about utilizing it and making necessary arrangements. You can install wall-mounted shelves or cabinets to store your essentials and save a bit on floor storage. Or, use vertical design elements like tall cabinets, wall tiles, vertical stripes, etc., to provide an illusion of more height in a bathroom.

Innovative Material Choices: Materials also help make the most of the available space without compromising style. As mentioned earlier, tall and large wall tiles give the illusion of ample space. Other than that, opt for sleek materials like glass shower doors to save space and provide an aesthetic look to your bathroom.  

Smart Technology in Bathrooms: Technology can also be a great way to optimize space; even minor changes can do the job. For example, sensor-activated faucets enhance hygiene and keep the space clutter-free without protruding handles. Sensor-activated cabinets also fulfill a similar purpose.

Small Bathroom Remodeling Layouts and Floor Plan Ideas

Design is a key aspect of a small bathroom remodeling project, making it feel more spacious and visually appealing. Following are the three best ideas for small bathroom remodeling with pictures you can take inspiration from: 

Small Bathroom With Bathtub

Bathtubs take up much space, so keeping them in a small bathroom might seem pointless. However, tubs might be essential for people who bathe their kids and pets. If you’re one of them, consider a low-profile tub. This allows a quick get-in and out and makes the bathroom more open. 

Orient the door outward to ensure maximum space inside and install wood-trimmed casement windows to add decor and airflow to the room. Also, install a wood cabinet to conveniently store toiletries and decor, like a green plant.

Small Bathroom With Washing Machine

This small bathroom remodeling plan suits a square space with a stacked washing machine. Similar to the previous design, you can install an outward or pocket door. The floating vanity sink and toilet provide a sense of space, while the storage drawers under the sink help stack your toiletries. To add aesthetics, keep the shower in a corner with a rounded glass panel.

Small Bathroom With Shower

If you have a small rectangular bathroom, follow the “three in a row” style, where the sink, toilet, and showerhead are on a single line. Install a floating toilet and a glass partition for the shower to make the bathroom spacious and easy to clean. As in the previous plan, keep the storage drawers below the sink and install swinging doors. A glass shelf above the toilet is good for keeping a candle, plant, or other decorative items.

How to Build a Small Bathroom Remodel

Learning to remodel a small bathroom DIY can be rewarding but complicated. It requires planning, designing, and building skills, as well as focusing on minute details. 

Phase 1: Demolition & Prepping the Space

First, a small bathroom rebuilding requires the right supply of materials. Although it varies with project type, the following are the staples: 

  • Safety goggles
  • Work gloves
  • Mask
  • Tape measure 
  • Hammer
  • Chisel 
  • Paint brushes
  • Knife
  • Drill
  • Circular Saw
  • Screwdriver
  • Wiring
  • Paint
  • Rags

Now that you have the materials per your chosen design, it’s time to remove the flooring, tiles, and fixtures. 

However, before you pick up the sledgehammer, shut off the water supply and electricity and put a protective cloth over anything you’re keeping. Remove moldings and baseboards, drain the toilet before removing it, and remove the bathtub, mirrors, sink, vanity, and others.  

Phase 2: Plumbing & Electrical Adjustments

Once the room is clear, begin the plumbing work. If you plan to relocate any fixtures, reroute the plumbing pipes. Plumb the shower tub or water supply lines, drain lines, and sink drains. Then, start with the electrical adjustments. You might need to run new circuits. Keep the outlet within 3 feet of each basin and along its length to be used comfortably. 

If you keep lighting fixtures above showers or bathtubs, ensure they are specifically rated for wet conditions. Make the final connections for lights, outlets, exhaust, and others. Both plumbing and electrical appliances need power to work. In case of a power outage or a rolling blackout, you’ll need a power source like Jackery Solar Generators. These have enough power to run most of your tools for hours.  

Please Note: Although plumbing and electrical adjustments are doable, they involve risks and are prone to damage if not handled properly. It’d thereby be wise to hire a professional for such tasks. 

Phase 3: Flooring & Wall Treatments

Once the plumbing and electrical tasks are complete, you can install and finish the flooring and wall treatments. Install a cement board and vapor barrier in areas prone to moisture and dampness. A cement board prevents moisture and is a good backer for wall tile. For other walls, use drywall. 

Moving on, install floor tiles that are waterproof, simple to install, easy to clean, and attractive. Common flooring materials include porcelain, ceramic, or plank vinyl flooring. Avoid using engineered wood, solid hardwood, or laminate flooring in small bathrooms. 

Phase 4: Installing Fixtures & Storage

It takes some time for the floor tiles and drywall to set firmly and dry. Once they do, install the shower tub. If you plan to install a shower enclosure, add a curtain rod or a glass shower door. Wait for the caulk and adhesives to dry completely, then install the amenities, like the vanity, faucet, toilet, and cabinets. 

Phase 5: Final Touches & Deep Cleaning

Now that you’ve completed small bathroom remodeling, it’s time to add the finishing touches of bath decor and any extra storage you need. Install mirrors, shelves, towel bars, and finishes that match the vanity hardware. Then, deep clean the bathroom. Spray an all-purpose cleaner on the surfaces and use a brush to scrub and make your bathroom as good as new.
