The Beauty of Natural Stone, Set by a Master Craftsman

Natural stone is the oldest and most enduring building material on earth. Long before engineered surfaces and synthetic tiles existed, craftsmen built with what the earth provided — marble, granite, slate, travertine, limestone, and quartzite. At Nautilus Design and Build, we carry that tradition forward. Every slab is hand-selected for its unique grain, color, and character. Every cut is measured with precision. Every piece is set into a properly prepared substrate that ensures it will look stunning and perform flawlessly for generations.

Levi Shewalter has spent more than 22 years working with natural stone across the Flathead Valley. That experience means he understands not just how to install stone, but how each type of stone behaves — how marble absorbs moisture differently than granite, how travertine requires a specific setting technique to prevent lippage, how slate needs careful handling to preserve its natural cleft surface. This is knowledge that only comes from decades of hands-on work, and it is the difference between a stone installation that lasts five years and one that lasts fifty.

We install natural stone throughout every interior space in your home. Our stone shower walls and surrounds transform bathrooms into spa-like retreats. Stone fireplace surrounds create dramatic focal points in living rooms and great rooms. Natural stone flooring adds timeless elegance to kitchens, entryways, and hallways. Stone accent walls bring depth and texture to any room. And stone vanity surrounds give bathrooms a custom, high-end finish that tile simply cannot replicate.

Understanding Natural Stone Types

Choosing the right natural stone is one of the most important decisions in any interior project. Each stone type has distinct properties that make it better suited for certain applications. Marble is prized for its luminous veining and classic elegance, making it a top choice for bathroom vanity surrounds, shower walls, and fireplace mantels. It is softer than granite and requires regular sealing, but its beauty is unmatched. Granite is one of the hardest natural stones available, with exceptional resistance to scratching, heat, and moisture. It performs exceptionally well as flooring, shower walls, and anywhere durability is a priority.

Travertine offers a warm, earthy tone with natural pitting that gives it an old-world character. It is popular for bathroom floors, shower walls, and fireplace surrounds. When filled and honed, travertine provides a smooth, elegant surface. When left unfilled, it delivers a rustic, textured appearance. Slate is known for its rich, layered colors and natural cleft texture. It is extremely dense and water-resistant, making it ideal for shower floors, bathroom flooring, and accent walls. Its natural grip texture also makes it one of the safest options for wet-area flooring.

Limestone provides a softer, more uniform appearance with muted earth tones that complement both contemporary and traditional interiors. It works beautifully for fireplace surrounds, accent walls, and bathroom flooring. Quartzite is often confused with quartz engineered stone, but it is a completely natural metamorphic rock that combines the beauty of marble with the hardness of granite. Quartzite is exceptionally durable and heat-resistant, making it an outstanding choice for kitchen applications, flooring, and high-traffic areas.

Natural Stone vs. Manufactured Stone

Manufactured stone veneer has become a popular budget alternative to natural stone, but the two products are fundamentally different. Manufactured stone is made by pouring pigmented concrete into molds. It can mimic the general look of natural stone but lacks the depth, variation, and character of the real thing. Natural stone features veining, mineral deposits, and color shifts that are impossible to replicate in a factory. Over time, natural stone develops a patina that adds to its beauty, while manufactured stone can fade and show its concrete composition as it ages. For homeowners who want authenticity and lasting value, natural stone is the clear choice.

Sealing, Maintenance, and Long-Term Care

Proper sealing is essential for every natural stone installation. Nautilus applies a professional-grade penetrating sealer immediately after installation that protects the stone from moisture infiltration, staining, and etching without altering its natural appearance. Different stones require different sealing schedules — dense stones like granite and quartzite may only need resealing every two to three years, while more porous stones like marble, travertine, and limestone benefit from annual resealing in wet areas like showers and bathroom floors. Levi walks every client through a simple maintenance plan tailored to their specific stone type and installation location.

Natural stone pairs exceptionally well with our other interior services. Stone shower walls are a cornerstone of our full bathroom renovations. Stone fireplace surrounds complement our custom masonry work. For clients who want the beauty of stone combined with custom tile patterns, our tile installation services create seamless transitions between materials. And for projects that combine stone with other premium finishes, our stone and masonry portfolio showcases the full range of what Nautilus can deliver.

Natural stone installation typically ranges from $15 to $75 per square foot for materials, with labor adding $10 to $30 per square foot depending on complexity. A stone shower wall project may range from $4,000 to $12,000 or more. Contact Nautilus for a free consultation and detailed estimate based on your specific project.

Yes, natural stone is excellent for showers when properly installed and sealed. Granite and quartzite are particularly well-suited because of their density and low porosity. Marble and travertine create stunning shower walls but require proper sealing and periodic maintenance. Nautilus ensures every stone shower is fully waterproofed with professional-grade membrane systems before any stone is set.

Natural stone is sealed using a penetrating impregnating sealer that soaks into the stone's pores without changing its appearance. The sealer creates a barrier against moisture, stains, and etching. Nautilus applies sealer after installation and recommends resealing every one to three years depending on the stone type and its location in your home.

Natural stone is quarried directly from the earth and features unique color variations, veining, and texture that cannot be replicated. Manufactured stone is made from concrete, pigments, and aggregates molded to resemble natural stone. While manufactured stone costs less and is lighter, natural stone offers superior durability, a one-of-a-kind appearance, and greater long-term value for your home.

Yes, natural stone is one of the highest-value interior finishes available. Stone fireplace surrounds, stone shower walls, and stone flooring consistently rank among the top features buyers look for in Montana luxury homes. Natural stone installations typically return 70 to 100 percent of their cost at resale.

Timeline depends on the scope and complexity of the project. A stone shower typically takes 1 to 2 weeks, a fireplace surround 3 to 7 days, and a stone accent wall 1 to 2 weeks. Larger projects like full stone flooring for a kitchen or entryway may take 2 to 3 weeks. Levi provides a detailed timeline before work begins so you know exactly what to expect.

Montana's extreme temperature swings and low winter humidity can affect interior stone, particularly near exterior walls, entryways, and fireplaces. The Flathead Valley can see temperature differentials of 100 degrees between summer and winter, which causes subtle expansion and contraction in stone and substrate. Nautilus accounts for this by using flexible modified thinset mortars, proper expansion joints, and appropriate membrane systems that prevent cracking and delamination over years of seasonal cycling.

Nautilus is a one-man operation led by Levi Shewalter with 22-plus years of hands-on experience. Every project is done by Levi personally — no subcontractors, no rotating crews. That means consistent quality, direct communication, and a level of craftsmanship that larger outfits cannot match. Levi hand-selects every stone, custom-fits every piece, and stands behind every installation he completes.

Yes, natural stone is one of the best flooring materials for radiant heat systems. Stone conducts and retains heat efficiently, making it ideal for hydronic or electric radiant systems popular in Montana homes. Granite, slate, and quartzite perform especially well. Nautilus installs stone flooring over radiant systems using uncoupling membranes like Schluter DITRA-HEAT that protect both the heating elements and the stone from thermal stress.
