Beneath the Surface—Crafting an Immersive Underwater Glass Mosaic in Seattle

A fully handcrafted glass mosaic mural beautifully showcasing a continuous and immersive underwater scene with deep ocean blues, vibrant pinks, and soft greens.

“We really wanted the space to feel as though you were standing underwater looking up. When the workshop integrated those reflective and iridescent tiles near the ceiling line, it instantly captured that magical feeling of sunlight hitting the surface of the water.”

— Jeanne, Homeowner

Project Type A custom bespoke mosaic for a residential bathroom shower and adjoining walls
LOCATION Seattle, WA
Design CollaborationMEC, Calista Interiors (Design Firm) & LZL Construction, Inc.
Area Approximately 160 ft² + some extension later on
Year 2025
Materials Hand-cut stained glass with iridescent and reflective accents

Bringing the underwater world to life, this hand-cut glass mural features reflective glass tiles, adding a striking detail of natural light sparkling through the ocean’s surface. Flowing effortlessly across three shower walls, this 160-square-foot mosaic artwork was constantly polished to ultimately capture the ocean’s depth in the most realistic manner.

Client Brief

It all started as a simple discussion regarding a customized kitchen backsplash which ultimately turned into something very interesting and ambitious. MEC was initially contacted by Calista Munnell, the main designer of Calista Interiors. She wanted to inquire about a unique kitchen design for clients Kent and Jeanne. 

Expressing that they loved our famous ivory and gold tree mosaic art, the homeowners first wished to replace the palm trees with foliage that seemed suitable for the Seattle area. Later, the clients wanted to completely change the orientation of their original vision.

They shared a very striking underwater wallpaper with us, which was used as an inspiration for an extensive custom bathroom mural. Here is the interesting part. This very first collaborative project of ours eventually guided MEC to another property, building a completely different mosaic story down the road.

Inspiration Moodboard

Before our artisans proceeded with cutting any glass manually, we made arrangements for and shipped a physical tile mood board straight to Seattle. What this vital step did was that it enabled Calista and her clients to take their time to compare the new glass shades with the current tones of their bathroom. 

Calista immediately approved the sample once she received the package, she told us that the samples looked ideal for her space, showcasing a diverse range of elements. This physical mood board encapsulated the soothing aquatic feel perfectly. It had: 

  • Subtle aquatic greens and teals to capture the sunlit areas of the water.
  • Deep ocean blues to create shadows, contrasts, and a feeling of true visual depth.
  • Simple neutral background tones to balance out the very vibrant colors.
  • Reflective finishes in order to replicate natural light hitting the water.

Although a mood board is a nice starting point in terms of setting up the general style, a glass mosaic artwork, especially one that is handcrafted, requires several more colors to blend smoothly. The wallpaper for reference was a great creative starting point, but a hand cut glass mosaic and a printed picture are innately quite different, needing thoughtful adjustments.

Design Development

Initial Sketches

At first the underwater mosaic was only being considered for one shower wall.

Briefly, the team talked about adapting the current pastel Koi fish mosaic, which would have saved time. However, they eventually went back to the underwater artwork that they were initially drawn towards.

With the project gradually developing, Calista and her clients intended to extend the artwork further. MEC was requested to take into account a few new possibilities for the room layout. This included:

  • Scaling the underwater mosaic design to make it easily wrap around the entire shower enclosure.
  • Repeating the core design identically after duplicating it on the two smaller side walls.
  • Using plain tiles to fade the design out on the sides through a subtle ombre fading method.

Being committed towards providing dedicated design consultancy, MEC suggested that a continuous wrap would result in the strongest visual appeal. If the pattern was repeated, it would have felt quite crowded. Also, an ombre fade could interfere with the visual language of the mosaic artwork.

Within her team, Nada advised wrapping the pattern around the central wall and two side walls. She explained that this option would help the artwork to flow in a natural and smooth manner. It would also make it fully immersive without any visual interruption. This approach turned out to be very helpful as it ended up becoming the foundation for the 160 square foot space.

Designing Around Architecture

The architecture of the room was quite unique, which also played a very main role in terms of shaping the final artwork. Given that the wallpaper was just not big enough to stretch across the whole area, a lot of compositional work and layering was required from our end.

In this context, another important aspect was the corner where the shower met the next wall. It was pointed out by Calista that the first design went from dark to light a bit too quickly. 

To fix this abrupt effect, our design team reworked on it in order to make sure that the artwork flowed more naturally. After this, Calista wanted more visual attention on the central shower wall instead of the side window wall, which was not clearly visible. 

Therefore, the required changes were thoughtfully incorporated accordingly, in order to address these concerns. Calista was happy with the revised design, stating that her clients would also be very pleased with the new changes.

Color Palette & Materials

The color palette contained soft shades of green, deep blues, and neutral tones.

With reference to the materials, we entirely relied on hand cut stained glass with special accents. Here, Jeanne came up with a lovely idea, which seriously enhanced the entire look of the artwork, once the upper portion of the mural was refined.

Right near the top, she wanted it to seem as if the natural light was reflecting through the surface of the water. MEC made sure to inform her that this creative input from her end would certainly be incorporated into the final composition. As our team utilized the natural reflective nature of glass to bring the underwater environment to life in the best manner, this concept became a central part of the material direction. 

Color Correction During Fabrication

Client evaluation continues even after construction has begun. As the pictures of the workshop were forwarded, Jeanne and Calista saw warm shades like yellow and orange in lower botanic parts. The color tones coordinated from the initial mood board earlier were not this warm. Instead of keeping the creative art fixed, MEC offered a choice of colors to be reconsidered.

Calista gave a different color combination, changing orange shades to pink, maroons and reds and keeping greens and blues the same. The colors were revised by the production team and Jeanne liked pink shades over browns. Moreover, there was a visible layer at the intersection of two walls that came to MEC’s notice. Instead of hiding it, it was completely revamped so that it looked natural after installation.

“Translating a printed wallpaper graphic into hand-cut glass is all about artistic interpretation, not mechanical replication. We have to consider how physical glass textures, specific color placements, and the room’s ambient lighting will interact to bring the aquatic scene to life.”

— MEC Design Team

The Final Site Adjustment

“Wrapping the artwork continuously across the shower walls and carefully softening the color transitions the mosaic felt like a true environment rather than just a picture hanging on a wall.”

-Calista Interiors

Finally, as mosaic tiles reach their destination, Mike and John, the LZL construction team opened it to begin the installation. Then, they learnt that two new supplies were needed.

Extra tile was needed along the lower edge, and another panel was required to complete a niche. To address these issues, MEC was quick to coordinate with Calista as well as the construction team. The purpose was to find the best solution.

It wasn’t practical to return the pieces to the workshop, hence MEC invented the extensions needed and supplied new glass tiles as well. This new material offered skilled installers the flexibility to allow little adaptations and changes. 

A New Chapter in Virginia

With Kent and Jeanne connecting us with Rosehill Design’s Amy, the interior designer working on their Virginia property, this collaboration naturally continued beyond this project. Now, we are collaborating with LZL, Amy, and the clients, on another bathroom. This involves a celestial shower wall and bathroom floor in marble with gold accents.

What began as a simple kitchen-related inquiry translated into a memorable underwater masterpiece, and a lovely continuation in Virginia. The Virginia project, however, is a story for another day.

FAQs

Surprisingly, it started with a completely different room! The clients initially reached out to customize one of our Ivory and Gold Tree mosaics for a kitchen backsplash. They later changed their minds and decided to focus on a much larger, custom underwater mural for their primary bathroom instead.

We treat reference images as a creative starting point rather than something to mechanically copy. A printed wallpaper and a handcrafted glass mosaic are very different mediums. Our artisans interpret the digital artwork using physical tile, texture, and light reflection to make it work beautifully in real life.

Yes, client review continues even during fabrication. In this project, the clients noticed some warm rust and orange tones in the lower coral areas that they wanted to change. We easily adjusted the palette right in the workshop to feature the softer pink, magenta, and rose hues they preferred.

It is common for field measurements to shift slightly. For this Seattle home, the installers realized they needed a back panel for a shower niche and a slight extension along the bottom. We quickly hand-cut the extra sections and shipped them directly to the site along with loose colored glass so the team could blend the edges perfectly.

Nada and the team at MEC did a fantastic job with our kitchen backsplash! We loved the Erassa design on their website and they were very accommodating with updating it to reflect our own preferences. After making a number of tweaks and approving the final design, we received the completed mosaic earlier than expected and packaged very well. The installation went smoothly and we love looking at it every time we enter our kitchen!

Zeeha and the entire Mec Artworks team were excellent to work with! I can't recommend them enough. We talked to lots of different companies when designing the custom mosaic for our pool, and Zeeha and her team were prompt, professional, and group we felt most comfortable proceeding with. We couldn't be happier with the quality of their end-product! The mosaic turned out beautiful, the communication through the process was reliable, and the installed mosaic is the centerpiece of the pool we were hoping for.

I found MEC online searching for a mosaic Persian rug for my bathroom. I found the Este Custom Marble Persian Mosaic Rug and loved it the way it was but the sizing needed to be tweaked a little. Nada got back to me right away and was extremely helpful with making the necessary adjustments to maintain the integrity of the rug to fit the space. Nada sent samples, videos and a thoughtful presentation of of the piece with mock ups of how it would look in the space. We were so thrilled with how the rug turned out. I am still waiting for the full install but could not be more pleased with the whole process, communications and quality of MEC's work. I would highly recommend MEC to anyone who is thinking about a mosaic piece. Nada, Zeeha and team were a true pleasure to work with. (Pictures to come!)

It has been a wonderful and fun experience to work with MEC on the design and execution of our kitchen mosaic. Nada was prompt and thorough with her replies, always giving us in-depth understanding and explanation when needed. We felt reassured throughout the whole process. Nada made sure that the end mosaic met our complete expectations. We were looking for more than a backsplash, and the mosaic created by MEC is truly a piece of art. This was an investment that not only pulled the room together, but also highlights a stunning piece of creativity. Very reasonably priced for the quality, beauty, and piece of art made with unique composition and creativity. Would do this again and again with MEC!

We have now completed two projects with MEC. The results on both a large bath and full kitchen were outstanding. The design team was a pleasure to work with, they completed and delivered ahead of schedule, and the quality of the murals truly added a unique and high-quality to the rooms. I will look forward to working with them again.
