Pool design is often evaluated through large surfaces and overall form. However, the true quality of a pool is hidden in the details. Especially in projects where Porcelain Tiles are used for pool cladding, corner turns, edge finishes, and transition points are not merely aesthetic choices but technical decisions directly related to safety, durability, and long-term performance.
At this point, Inner Trim and Outer Trim are among the most critical yet least discussed components of pool architecture. Corners assumed to be solvable with flat tiles can become sources of both visual and structural problems over time. For this reason, the use of inner and outer curved elements is essential for pools.
Inner Trim and Outer Trim are specially shaped structural elements used at pool corners and edge transitions to provide continuity that flat tiles cannot achieve.
The main purpose of these pieces is to eliminate hard and sharp junctions and ensure smooth transitions between surfaces. However, their function goes far beyond this.
Due to their material properties, Porcelain Tiles offer high hardness and low tolerance. While this provides advantages on flat surfaces, it requires precision at corners and turning points.
Corner solutions created with flat tiles:
Inner and outer curved pieces aim to eliminate these risks at the design stage. By ensuring uninterrupted surface flow, the cladding becomes more balanced both structurally and visually.
Pool safety is often evaluated based on Non-slip surfaces. However, corner and edge details play an equally critical role.
Sharp corners:
Inner Trim provide soft transitions at wall–floor junctions, preventing sudden contact with hard surfaces. Outer Trim make edge lines safer and create controlled transitions between walking areas and the pool.
In pool projects, aesthetics are measured not only by material quality but also by how well details are resolved. Choices made at corners and edges define the overall visual quality of the pool.
Inner and outer curved pieces:
Sharp turns created with flat tiles produce a visually fragmented effect. In contrast, curved solutions allow the pool to be perceived as a single, cohesive form—especially noticeable in architectural photography and spatial experience.

Porcelain Outer Trim are complementary structural elements designed with an outward-curved form to soften pool corner and edge transitions while maintaining surface continuity.

Porcelain Inner Trim are special porcelain elements with an inward-curved form, primarily used at wall–floor junctions inside pools, eliminating hard 90-degree corners.
Inner and outer porcelain curved pieces are not merely complementary elements but core components that ensure the proper functioning of the Pool Edge System. By eliminating sharp corners, they enhance user safety and support long-term surface durability. These elements balance grout loads, simplify maintenance, and give the pool a more fluid, readable architectural form.
Swimming Pool Steps are among the most critical areas for the application of inner and outer curved pieces. Step front edges, turning points, and side surfaces require special attention in terms of both aesthetics and safety.
In these areas, curved pieces:
Especially in projects using Stair Non-Slip , these pieces form an integrated system where surface texture and form support each other.
Inner and outer curved pieces are often overlooked but are fundamental elements that carry the project. They do not simply complete the cladding; they ensure the system works correctly. Their placement should be evaluated within each project’s context, considering usage intensity, pool geometry, target users, and architectural language.
Are inner and outer curved pieces necessary for every pool?
Not every pool has the same structural characteristics. However, in projects with corners and steps, these elements offer significant technical advantages. They should be strongly considered when safety and longevity are priorities.
Are these pieces used only for aesthetic purposes?
While their aesthetic contribution is visible, their primary functions are structural continuity, safety, and application stability. Aesthetics are the natural result of these technical benefits.
Can inner curved pieces be added later?
Theoretically possible, but not ideal. These elements should be planned during the design phase, as later additions may compromise overall integrity.
