Designs for All Generations

Universal design encompasses and addresses the needs and abilities of people of all ages. Sometimes referred to as “multi-generational design”, it combines safety and comfort with style and beauty to create an end product that is attractive, versatile and practical. Universal Design principles are especially applicable in the bathroom, a space that even the most able-bodied person can find difficult to navigate at times. By giving careful consideration to space planning, accessibility, security and privacy issues, smart designers can create a bathroom environment that promotes independent living for every member of the household. Multi-generational design doesn’t mean “institutional” design– it simply means being smart and stylish at the same time. Toward this end, MTI offers a broad selection of bathroom products that will enable household members to avail themselves of the power of water to sustain, heal and renew. With MTI’s design flair, it is possible to incorporate comfort, practicality and a modern sensibility into a bathroom and at the same time accommodate every member of the family with ease and safety. With increasing numbers of families having more than one generation sharing a roof, it is becoming more important that homes be designed to meet the needs of different age groups. Multi-generational, or universal design is intended to benefit everyone, including the elderly or physically challenged. A universally designed bathroom strives to be accessible and comfortable over an extended period of time for all members of the household. Within the environment of the bathroom, aspects influenced and impacted by this design approach include:
  • Floor space maximized for safe navigation.
  • Tubs and showers designed, positioned and installed for easy and safe entrance and exit.
  • Sinks designed and installed for easy access.
  • Floor and tub/shower surfaces that are anti-slip.
  • Easily accessible resting places.
  • Conveniently and strategically located grab bars for safety and security.
While there are many practical considerations that play an important role in the universal design process, such as safety, space, comfort and ease of use, being “sensible” doesn’t mean that the bathroom has to look utilitarian. Quite to the contrary. Universal design is good design. Click here for information about MTI products that are ADA-compliant for municipal and commercial purposes.

Shower Systems

A solid first step in creating a multi-generational design bathroom is to assess as best you can the current and projected needs of the people who will be living in the space. Whether embarking on a new construction or a remodeling project, the design of the space and the selection of product should be a reflection of those who will live in and use the environment. Depending on the lifestyle and requirements of household members, the options can vary. While new constructions generally include a tub in each secondary bathroom, do bathrooms for teenagers or guests really require tubs? And even though most people think “tub” when planning a remodel for universal design, this may not be the only or best choice. In designing a bathroom that is truly multi-generational, or universally user-friendly, showers emerge as the “unsung hero” of this endeavor, providing an attractive, versatile and functional solution to the challenge. Accommodating Shower Systems Why are showers multi-gen design-friendly? Three good reasons:
  1. Transfer ease. By their very design, shower bases are easier bathing vehicles to enter and exit than tubs. Any shower base has a shallower threshold to step over than the wall of any tub, thereby requiring less dexterity, regardless of bather age.
  2. Transfer time. A shower allows one to start the water running and adjust it to a comfortable temperature in advance.
The combination of these two factors decreases the amount of time the bather is subjected to the ambient air temperature of the bathroom while unclothed before entering the warmed water environment. This is especially important for a person who has mobility impediments. The time it takes to enter a shower with a modest or zero threshold is much less than the time it takes to navigate over the wall of a tub, and then to lower oneself – or be lowered – into the warmed bathwater.
  1. Resting possibilities. Showers afford a variety of options for providing seating areas as a resting place during transfer or during the actual showering process. This is also a very nice convenience for women when shaving their legs. Seating areas can either be integrated in the shower base itself, or seats can be positioned inside as well as outside the shower. MTI’s shower seats are constructed of genuine teak with stainless steel hardware, both of which can withstand the wet environment of the shower. MTI Teak Shower Seats are wall-mounted and can be folded-up, out of the way when not in use.
MTI excels in providing assistance and solutions for all of the areas cited above. MTI’s comprehensive range of shower bases includes over 75 models in various sizes, shapes and materials. Some are constructed of Engineered Solid Stone® material, which is a mixture of ground minerals and high-performance resins that are liquefied, poured and then hardened. The matte surface meets ANSI standards for slip resistance. These “molded stone” bases feature a low-profile, multiple-threshold design for versatile installation, great looks and easy access. These bases are high in both design and function. Other bases are constructed of cross-linked cast acrylic with strong reinforced backing to eliminate flexing of the floor pan. They are attractive and easy to clean. Some are single threshold, and others are low-profile, multiple threshold, which means that they can be specified from the factory to accept glass enclosures on one, two or three sides. The low-profile design not only presents a very clean look, but it also makes entrance and exit easier. As a standard feature, MTI acrylic shower bases include a slip-resistant textured bottom that meets ASTM F-462-1994 certification requirements for safer showering. Taking this one step further, if a zero-barrier entrance is desired, the low-profile, multiple threshold bases can easily be recessed in the floor. When used in combination with a teak shower tray, a flat, barrier-free transfer surface is created between bathroom floor and shower. Another alternative for a zero-barrier entrance are MTI’s  Barrier-Free Shower Bases in various sizes, both seated and unseated, made specifically for easy, seamless transfer from bathroom space to shower. Constructed with slip-resistant bottom, the front threshold is a mere 1-3/4″ high, which is designed to be recessed in the floor, creating a flat transfer surface between bathroom floor and shower floor. A special drain design with stainless steel grate cover efficiently drains water to the center. Complementing MTI’s extensive assortment of shower bases are shower enclosures with a true frameless design and no old-fashioned headers for a clean, uncluttered appearance as well as convenient entry and exit, even for tall persons. Glass doors and panels are constructed of very substantial tempered safety glass. For strength and durability, hardware is made of cast brass and attaches through the glass to ensure security and long-term proper alignment.

As we have already established, multi-generational or universal design focuses on those who will be living in and using the space. This means that product selection needs to be based on more than aesthetics. Products must match the abilities and meet the requirements of the users. If a tub is what is needed, desired and preferred for the bathroom, MTI is the comprehensive source, with over 200 available tub models in all sizes, shapes and styles. With MTI design flair, comfort and practicality do not need to be sacrificed when designing a bathroom for multi-generation use. If your specific requirements call for a very shallow tub, MTI has several models that are only 19″ high or less, making entry and exit a more user-friendly and a little less challenging. There is one tub group of particularly beautiful and clever tub models that need to be highlighted:  the Metro Series. The three Metro models are of clean, contemporary design and feature a generously wide front deck of 11″, which serves as a convenient transfer surface. The bather can sit down on the edge and then turn into the tub instead of climbing over the tub wall. The functionality of this wide deck feature is further extended when the Metro is installed with an available coordinating contemporary tub surround that has been designed just for this model. This handcrafted furniture piece complements the tub and provides additional storage and decorative display space recessed in front under the wide deck area. Matching vanities are available in a variety of sizes to complete the ensemble. The Metro Suite is an outstanding example of how a product can be beautiful and simultaneously serve the needs of many. MTI also offers additional possibilities for resting places for use with tubs. One tub seat model available is designed for Andrea Series® tubs and the Madelyn 1 tub. Madelyn 1 features flat armrests, and Andrea Series tubs can be specified with armrests at the time of tub ordering. Since the armrests are flat, they serve as an ideal place for the teak tub seat, which provides a convenient resting place when bathing or hand showering. Shown to the left is a second type of teak tub seat which provides a convenient transfer surface as well as a resting place during hand showering. It mounts to the wall and can be folded up when not in use. Three sizes are available: 32″, 36″ and 42″ widths. For those who want or need a tub and are challenged by mobility factors, MTI’s new Walk-In Tub can provide a solution. This tub offers a host of features: MBWI5030 Walk-In tub measures 50.625″ x 30″ x 36″ and is available with a right- or left-hand drain. Welded steel frame with adjustable leveling “feet”.
  • Standard equipment:
    • Virtual spout high-flow tub filler eliminates potential obstacle of a filling spout for mobility-challenged individuals.
    • Fast drain with quick-release drain stopper and chain.
    • High-quality hot and cold high-flow valves with handles.
    • Hand-held shower with diverter.

Tub Options for Universal Design Bathrooms


MTI offers a number of enhancements that can significantly contribute to the comfort and safety of the bathroom environment. Listed below are some of the more popular options. Grab bars increase safety and security for all family members. Position them strategically in the bathroom, inside and/or outside the tub or shower, or wherever additional stability and assistance may be needed. Available in a variety of sizes, materials and finishes, grab bars are designed to be both decorative and functional. Properly positioned, they are a smart, preventative addition that people of all ages will find helpful. Important: make sure that grab bars are fastened directly to wall studs for safety and security. Neck pillows available in a variety of shapes, are made of soft, durable vinyl and provide support, comfort and relaxation. Radiance® Surface Heating System technology uses radiant heat in acrylic bath tubs to warm the interior surface of the bath for neck, shoulders, back and bottom. It provides an even distribution of warmth to eliminate the shock of a cold tub and increases relaxation during the bath. Radiance can also be installed in the seat and floor of seated shower bases. Virtual Spout is a high-flow tub filler that takes the place of a traditional spout. Not only does it contribute to aesthetics, but it also allows the use of more space in the tub and eliminates a possible source of injury. Textured Bottom provides a slip-resistant surface and meets ASTM F-462-1994 certification requirements.



With all of the possibilities available for the size and style of the tub, it is easy to lose track of the primary reason for choosing a tub over a shower.  Both a tub and a shower are means for cleansing the body and maintaining hygiene, but a tub has the ability to offer hydrotherapy to promote wellness and assist in healing. MTI offers 4 distinct forms of hydrotherapy to meet the varying needs of household members one and all.  So as a multi-generational new construction or remodeling project is being planned, it is wise to give thought to the various types of therapy that may be desired or needed in the household.
  • Simply soaking:  The most fundamental form of hydrotherapy which uses the buoyancy and warmth of water to promote relaxation, rejuvenation and tranquility.
  • Whirlpool bath:  Provides deep tissue massage through jetted water mixed with air.
  • Air bath: Yields a light full-body massage by millions of tiny air bubbles that come from air jets located on the bottom of the bath.
  • Combination whirlpool / air bath:  Offers the flexibility of using either or both therapies, or using the tub for simply soaking.
MTI is one of the few manufacturers to offer this range of hydrotherapy choices over such a large assortment of tub styles, shapes and sizes.  Coupled with an extensive array of options, wide product range and intense customization capabilities, MTI is a rich resource for products that will support and facilitate a multi-generational design approach to the bathroom.
